Run the console app to delete all files and folders within the 'NinjaTrader 8> db> cache' folder.

The NT8 data cache folder saves pre-formatted data to suit your bars types, the purpose of which is to enable faster startup times.
Sometimes in certain circumstances your chart bars will be full of errors, so it doesn't hurt to clear the cache once in a while, or every day if you are having issues.

Use only if you are having problems with data, tick replay indicators or if you have modified your bars types.

This will NOT make a backup of your cache files, so use carefully!
It WILL, however, check for NT8 being open and advise you as such. It WILL check for your cache folder being empty and advise you as such.

This was built using an English speaking culture on Windows 10. It directs the delete command to:
'yourDocumentsFolder\NinjaTrader 8\db\cache'. This will not work on XP. Although I have tried to use code to work on all cultures, I have not tested it as such.

Thanks to bobc635 for suggesting this simple concept.

Tips:

* Extract the file to the desktop and run from there.
* If you wish to see inside the .exe file just download a free decompiler like DotPeek.

Delta Package V2


DeltaV3 is here

Updated to NT8b13 Oct 2016

Based on GOM delta indicators.

Includes:

* Both cumulative delta and bar delta.
* BidAsk.
* UpDown Tick.
* UpDown Tick with continuation.
* UpDown One Tick with continuation.
* Gom Hybrid.

Also other options:

* EOD/ new session reset to zero.
* Inverse delta - plot the 'Limit' orders.
* Size filter.
* Candle outlines.

Make sure you enable Tick Replay to use this historically! You will not need Gom recorder for this.

However, Tick replay will not work with some Renko bars due to RemoveLastBar()

Thanks to Zondor for his 'unGom' conversion.

Please report bugs to me via PM rather than in the comments. Thank you.

Delta Package V3 NT8.0.2 now with commitment of traders (COT) and heiken-ashi

Update Feb 2017: Changed "Show above / below EMA colors" to false to avoid confusion.

Minor fix 30 Dec: Added ability to change bar width manually. Note, if you have any custom built strategies using DeltaV3 then you will have to adjust your code as per the strategy sample included.

New: Sample code for use in a strategy is included. The strategy does not do anything, it simply shows how to access the delta values. It works, I've tested it. Make sure you use TickReplay on your host chart if you want historical values accessed within a strategy.

Includes everything from V2 here as well as these additions:

1. Commitment of traders: high, low and total.
2. EMA plot: Set to normal, gapless and reset at session open.
3. Heiken Ashi: Chose from the algorithms of Dan Valcu (standard) or Sylvain Vervoort.
4. Painbars based on delta values or above/below the ema.

Plus general improvements......

Make sure you enable Tick Replay to use this historically! You will not need Gom recorder for this.

However, Tick replay will not work with some Renko bars due to RemoveLastBar()

*Occasionally if the bid/ask plots don't look quite right, especially if you haven't connected for a few days, make sure you right-click on the chart and select "Reload all Historical Data".

Here is a picture of how you can use delta for your trading.
