Hi. I am setting up an indicator and strategy with Bloodhound and Blackbird and wanted to use in it Priceactionswing oscillator.
I receive the following error:
Time Category Message
7/6/2020 12:30:53 AM Default Indicator 'PriceActionSwingOscillator': Error on calling 'OnStateChange' method: Object reference not set to an instance of an object
I use Tick Charts in NinjaTrader 8 for Forex currency pairs.
I also use the PASPro indicator.
PASPro won't show on a chart for certain combinations of ticks per bar and currencies.
For example, PASPro won't display on a 100-tick chart of the GBPUSD. It will display at 75 ticks per bar, and at 150 ticks per bar. In other words changing the Tick setting on the GBPUSD chart from 100 to something else causes PASPro to appear on the chart.
Sometimes this effect can be changed by modifying the number of days loaded in NinjaTrader, but this is also a problem, as having to load many days when one is displaying short-term charts is slow in both loading and chart calculation.
This is very strange. It should be working. You can check to see if the 'Swing size' is correct or compare the swings on the chart to the PAS Oscillator (below the chart after installing, comes with the same package) to see if the Oscillator behaves the same.
Dear Mich62,
Thank you for your help in this matter.
1. Changing the ‘Swing size’ makes no difference to the problem.
2. The PAS Oscillator is not affected by the # of days loaded, and works normally.
3. I’ve made a video of a new chart of the GBPUSD with only the PASPro and PASO loaded.
The video shows the effect of loading from 1 to 10 days of data.
As you can see, PASPro disappears when 1, 5 and 8 days of data are loaded.
In case I can't upload, here's a 4-day expiring link to the .wmv file: https://onedrive.live.com/redir?resid=7EB5D0A4490F42A1!534922&authkey=!AGPfZz6bCfTLtpA&ithint=video%2cmp4&e=MQPGIQ
The machine has the latest version of NT8 and all Windows 10 updates installed.
I look forward to your further assistance Mich62
Yours sincerely,
David McMurray
Because the Oscillator is not effected I assume a bug which occurs as a result of (a specific combination of) used properties/settings.
For this you will need to contact the developer (dorschden?).
What you can do is to deselect the properties/settings you use one by one to try to identify which one is causing the problem. There is still a chance the problem occurs with all settings deselected.
I believe the version you are using is not accurate and therefore I use another version made by Poncho which I cannot find anymore here on the forum (think he deleted the files). This version doesn't have the problem (and shows slightly different values), however, it doesn't have all the settings (and that's also why I think it's in the settings).
I see 3 options you can do:
1) try to identify the setting you use which causes the problem (if it is a specific setting that is causing the issue).
2) contact the developer.
3) try another version of PAS (there are different versions in circulation)
Look at my video. Some days load very fast (maybe because of the weekend) and some take more time to load. Days 6 and 7 are loaded quite fast while day 8 takes some time. It seems there is something causing difficulties. In my case the data is still loaded but in your case the program is unable to (due to a bug).
Attached the PAS version I am using (from Poncho with less settings) and a video. Hope it helps. Good luck.
Thank you so much for the time you've spent helping me, and for the video and indicator files.
I've looked at the indicator's settings, but haven't found anything that affects the problem yet.
When I open my NT8 workspace, it's not always the same charts that don't load PASPro. I just opened my workspace and 6 of the 8 charts didn't load the indicator correctly, but it's usually only about 3.
I've attached a screen shot of the NT8 log that shows a number of errors involving the PASPro indicator.
I tried importing your version of PASPro but ran into the problem highlighted in yellow in the attachment, so I think I'll take up your suggestion of contacting the developer, dorschden. Can you tell me how I would do that please Michel?
For the indicator (which I attached) to install you need first to remove all of the existing indicator. I think you will find info in the thread and maybe in the download section of the indicator. You can also use the search box on the home page.
Hello All: This thread represents a tremendous amount of work and I thank you all for building it. I am working my way through your amazing work, and I will try to keep my questions to a minimum as I'm sure the answers are here, I just haven't reached them yet.
I am attaching a screenshot of the indicator (along with some other indicators).
I have four questions:
1. On the oscillator, what do the vertical lines measure?
2. On the oscillator, what does the redline represent?
3. On the price chart, what do the three lines of numbers represent?
4. Can someone point me to a thread that goes into "how to use" the indicator(s)?
Thank you in advance for your help.

The following user says Thank You to DonStar for this post:
Ad 1. Cumulative volume (of the swing)
Ad 2. Cumulative volume building up during the swing. Is not definite yet as long as the swing is underway
Ad 3. Not sure, you try it out by hiding the properties. Probably something as ticks, volume, time
Ad 4. Subscribe to David Weis free daily newsletter ( weisonwyckoff), watch his videos (here on FIO) and read his book.

@DonStar, I wonder how far you read this thread. The first post provides this information:
Swing values:
Here you can choose which information the swings should display.
Information:
- Duration (in bars)
- Labels (HH, HL,…)
- Length (in ticks, points,…)
- Percentage (in relation to the last swing. e.g. 100% = DT/DB)
- Time
- Volume (Absolute and relative. Relative is the average volume per bar)
Hope you at least read to there - about half way down the post. If you just happened to miss that - then ignore this comment.
I will mention that I believe the colors for the ABC visualization entry lines are reversed and should be changed. They are the thicker lines at the right edge that started green and then went to a long red. Switch those colors. Although someone said if it is red it means that the entry failed, I like the colors reversed.
I do not use the oscillator but from your image it looks like those colors are reversed also.
jmont1: You are correct. I guess there was so much information in the thread that I just did a cursory review of the first post. I appreciate your assistance (and your admonishment). I am going through this thread much more carefully now. Also looking into whether colors are reversed.
If you look at the code you will notice the stepped Red line that you marked is simply an average of the last swing volume.
I have no idea why it is included (almost redundant to the volume plot itself). But it is a visual indication of what David H. Weis calls "SOT" (Shortening Of Thrust), or simply deceleration of the upward move and a possible reversal when steps are getting very small.
The horizontal green bar across the vertical red bar on the oscillator is the volume of a possible start of a new swing up. But because the swing up is not completed (not 7 bars finished yet) it's still possible that price will come down again and then the swing down will continue. As soon as the threshold for the swing (in your case 7 bars) is exceeded the swing up is completed and the oscillator will turn to green from the first horizontal green bar that was printed across the vertical red bar. So the green bar is the cumulative volume of the swing up in the making.
I am not sure but I think when you set "Calculate on each tick" it's updated in real time and there will be no overlap of red and green bars visible.
The following user says Thank You to Mich62 for this post:
You might say that however there is no predicting in this. The trend is possibly already changing (we don't know yet) as you can see at the last three green bars up where you wrote "price rises". If price decreases again the down swing will continue (and the green line will disappear). If price keeps rising there will be a green wave printed on the oscillator showing the (definitive) rising cumulative volume of the swing up after it is finished (after 7 bars).
No. There is no buying or selling volume. What has been sold is also bought and vice versa. Don't mix this up with buying at the offer or bid!
This green bar is volume of a possible swing up (in the make) which is not finished yet. You want to know if this swing up is on high or low volume (to be able to compare to volume of prior swings and the range of the swings to determine if it is a pullback or maybe change in trend). If the cumulative volume of the swing would be shown after the swing is done you would not have a clue until the swing is done.
It's just the total volume per swing (up & down bars).
All volume (green and red bars) will be added (cumulative) to a total volume volume per swing. As soon as the swing up is finished (as defined after 7 bars) there will be a green wave printed.

Can someone add VPA signals to the swings of PAA such as No Supply or No Demand? Or import the VPA signals into PAA, the updated VPA indicator attached, it now has value plots in Market Analyzer and Strategy Builder.

@Futureskill, would recommend you provide a screen shot of your indicator settings. From your description the only thing I could suspect is that you are need to include the ".wav" file suffix in the name the way it is in the samples.
Is there a way to configure this indicator or any similar indicator to replicate Ira Epstein swing indicator? I leave video so you can see how his swing indicator marks the highs and lows.

@aja1946, this video did not focus on explaining the fundamentals of his swing indicator. It shows the arrows but does not explain them. My guess is that you have not really looked at PAS to see that it will show highs/lows as well as higher highs and lower lows.
Please experiment with the indicator settings. Then find a video that explains his system. Now expound on the inherent differneces of PAS to Swing and try to offer a reasonable modification to bring them in line.
There is not such video. It´s not difficult to compare how his indicator marks the swings and to deduct the differences with a regular swing indicator, that is the easy part. The difficult part is to program the differences in the swing indicator because PAS or NinjaPriceAction do not offer the necessary adjustments to do it.

@aja1946 from the video it looks like his swing is just using a swing size of one (1) rather than PAS where people usually look for longer periods before declaring a new swing.
Try going to "parameters" just above the Data Series. Change the Swing Size to one (1) then try tick instead of standard or other options to see if it matches over time. You could do it and look back at his older videos to confirm the match also.
Settings size to 1 and in type "percentage" doesn´t cut it completely. For instance, weekly candle in the ES-emini on September 18th, in Ira´s indicator there is a swing. The reason is that even though the candle closed lower than the previous candle, it has a high that is higher than the open of the previous candle. Some programming adjustments need to be done for that, I believe.
Using PriceActionSwingPro, Nt8, is not drawing the swing for the candle of September 18th, settings type "percent" swing size "1". Data Series: price based on "last", type "week", value "1". Trading hours "Use instrument setting".
it should work with both. another question. what's your background color and what's your lower high color? maybe both white? it would be a lot easier if you would post a screenshot of your chart.
Now it´s working. It´s weird. I did click on "use close values", then I did deselected "use close values" and it worked. Thanks Jmont and Silvester for your help.
if you use close values, then there's no lower high on sept, 18 because the close is not at least 1% higher than the last swing low. if you want to use highs and lows of the candle, do not select "use close values".
Now, if you look at the weekly candle of October 30th in the ES-emini, the bar is ignored by the indicator. This also happens in the chart that you posted, Silvester. Not sure if this is because there is a bug or because the adjustments.
Please explain how to get from Priceactionswing indicator by the request from another indicator:
1. Most recent trough/peak value
2. Number of bars since it
3. 2nd most recent trough/peak value
2. Number of bars since it
Thank you for this great tool. I am attempting to install in NT8, fresh install, but getting an error on the SimpleFont textFont = new SimpleFont("Courier", 15);
YOU KNOW WHAT WOULD BE AN AWESOME FEATURE for the Price Action Swing indicator?
If it would count ALL the swing lengths of that day >>> and then give the total amount of TICKS in swings that the instrument traveled or moved that day.
That way we can compare the amount of ticks that you got at the end of the day >>> with the total amount of ticks that the market moved for that day or trading session.
for example let's just say hypothetically >>> a market is sideways >>> and also hypothetically >>> it only moved 3 'swings'.
It moved up 15 ticks.... down 20.... then up 15 again >>>> just throwing completely random numbers out there.
So this market moved 50 ticks total >>> 15 + 20 + 15 = 50 ticks.
Lets say you are a starting trader >>> and you were able to get the UP swings >>> then you have 30 ticks ( minus spread in real life... etc. )
So you got 30 ticks / 50 ticks = 60 % of the trading range / volume
if you are more professional then you would have also gotten the other direction and been closer to the 50 ticks.
So basically the goal is to keep getting higher and higher in percentage of ticks of the day.... or trading session. Like you trade only the U.S. Open Session

@OAlejandro314159, I think that might have been a capability in NT7 version as statistics. It could estimate average swing sizes for a period. Unfortunately it was not carried over to NT8 version.
Run NT7 and see if it is what you are looking for. IF so then maybe someone could either add it to PAS or create it as a new separate indicator which I would prefer.
I share my edition bc it'll take eternity to explain this. I use this in my strategies. Code is pretty simple really. Everything that marked as "garbage" is my code so you can compare to original.
Add this to your indicator/strategy:
Make own variables to call values like this:
//3. 2nd most recent trough/peak value
//2. Number of bars since it
You should use UpFlip and DownFlip.
Store your current swing low price/length/bar in another variable so when DownFlip == true it becomes your old swing low.
I think it's possible to access to historical swings high/low within PAS but honestly I don't know how. I use UpFlip/DownFlip and it's works like a song.
He is a pic of showing those flips. Red arrows are first bars of swing down. Green - swing up. Swing size == 7.
I hope it helps.

I see there are Dots to point the Swing Hi/Lo. Is there an option to show vertical line instead of the dots. just like in the pictures attached.
thanks
andrey.
The indicator already prints the volume at each swing point. However, is it possible to print the "delta" volume at each swing point? That piece of information would be invaluable.

If there is indeed an official new one, please get my attention so I can update the downloads section and send out notices.
Sent using the futures.io mobile app
@Big Mike, I believe there's an updated version somewhere that never made it to the download section:
dorschden View Post
I'll fixed the code in a way that the divergence should work no matter how many bars are loaded. I have sent @Big Mike the updated version almost two weeks ago, but he didn't came around to upload it here in the forum until now. I can't upload a new version myself to the Free Section in the download area.
I am using Price Action Swing Oscillator as a part of a strategy I'm testing out with walk forward/live testing, but the indicator is currently repaints. For this reason, I have experimented with using smaller swing settings, but would prefer the larger swing settings (8 or 9).
1. Is it possible to have this indicator configured NOT to repaint?
2. Is anyone aware of a Weis wave for NT8 that does NOT repaint, in case it is simply not possible to get around repainting?
I am attempting to use the PAS indicator to code my own strategy but I am running into some issues/questions.
1) I'm working on the buy side now and I have successfully got the strat to enter a BuyStopMarket order after the HL prints but my issue is since the indi repaints, I am getting a lot of stop outs even with a offset Buy Stop order due to the nature of the repaint. Is there a way around this, or is there an exposed variable I can call on for my strat that will only look at the "final" paint value?
2) Also, around those same lines I want my strat to read in the volume values for each swing and based on a criteria...it will either take the buy or pass on the buy based on some simple if/then logic. Essentially a filter if you will, to filter out not so great trades. I have yet to find a variable in his PAS code that will expose the volume info that I can use in my code. Is this possible? And if so, how can I also use it to avoid repainted volume data?
3) Thirdly, has anyone tried using this PAS indicator on Blackbird and done these more advanced strategies successfully? I'm toying the idea of giving Blackbird a free trial/demo to code this strategy for me and instead of me doing it by code alone but don't want to waste time if its not going to work.
In case you were curious...here is my SUPER BASIC buy logic I am working with right now......
