Powerlanguage and Multi time frames

Laurent · November 27th, 2010, 12:59 PM

Hello!

I wanted to know if it is possible to use multi time frames in a function / indicator on MultiCharts / TradeStation.

Let's take an example. I want to create an indicator which will buy when the daily, the weekly and the monthly RSI are oversold.

Is it possible to do that? How? Is there some documentation/tutorial about it?

You simply load a chart with with the same symbol three times. Place each symbol on it's own subchart and timeframe. Place the daily as the primary chart to trade from. Place the weekly on subchart 2 and the monthly on subchart 3. You can then access all timeframes within a function (RSIalert) as demonstrated below.

Code

Variables:
  ReturnValue(false),
  RSIDaily(0),
  RSIWeekly(0, data2),
  RSIMontly(0, data3);


RSIDaily = RSI( Close, 14 );
RSIWeekly = RSI( Close of Data2, 14 );
RSIMontly = RSI( Close of Data3, 14 );

If ( RSIDaily < 30 )And ( RSIWeekly < 30 ) And ( RSIMontly < 30 ) Then
   ReturnValue =  TRUE
Else ReturnValue =  FALSE;

RSIalert = ReturnValue;

Hi and thanks for this example.

I have a similar problem and have tried similar solution as yours but get wrong result and can not get why?
Here is my problem:
I have written a function called "Rico.F" that is true if Close<Range*0,1 and are lowest low then 5 last period.
Then I want to buy when yesterday (daily chart), AND first hour at next day (1-hour chart), AND frist 15-min after that first hour (15- min chart) all have Rico=true.
I have 15-min as data1, 1-H as data 2 and daily as data3.
As I can see, just the 15-min Rico is correct and I cannot figur out how the code can get true result for those other in my result.
Is this some issue that you recognize?
Thanks for any clue in advance

Var:
Rico(False),
RicoD(False, data3), //ricoplus igar
RicoH(False, data2), //ricoplus 1 timme
RicoM(False), //ricoplus 15 min

//Rico
Rico = False;
RicoD=Rico.F(3)[1];
RicoH=Rico.F(2)[1];
RicoM=Rico.F(1)[1];
If RicoD and RicoH and RicoM then Rico=True;
End;

//Buy
if Ricop and marketposition = 0 then buy this bar at Close;

And Function Rico.F ***************************************************''

Inputs:
DataSerie(Numeric);

Var:
Rikoschett(0),
Lowest6Day(False),
BarRange(False);

//Lowest Low 6 dagar
If Low of data(DataSerie)<Lowest(Low of data(DataSerie),5)[1] then Lowest6Day = True;

//Rikoschett
Rikoschett=0;
If Close<((Range of data(DataSerie)*0.1) + Low of data(DataSerie)) then Rikoschett=1;

//Signal
Rico.F = False;
if Rikoschett=1 and Lowest6Day then Rico.F = True;

ShahramTor,

I would start with tying the functions to the datastreams when you call them. If you don't do that, they will be computed on data1 (although they use some values of your other datastreams).
You should be able to find examples for that here in the forum or in the help files (the last lines of this article show how to do it for example: FundValue (Function)).

The next step would be to add print statements to your code, so you can find out what values it uses and where it goes wrong.

Thans for your replay,

As you mention, I have a parameter in my function "DataSerie" which is the number of data stream.
I pass the numbers 1 to 3 for data1 to data3.

Do you see any thing wrong in that code or do you mean that it is not the correct way to make the function using different data stream?

Best regards

Please refer to the link I posted above and you will see how to tie the function to the datastream (which is not what you do with your code - it's missing that). Not tying the function to a specific datastream will result
in the function being executed in alignment with data1. This means that accessing a function value of [1] would give you the value the function had on the previous data1 bar and not on the previous data2 or data3 bar as you might expect. If you are fine with that, then no changes would be needed. In that case I'd still suggest to add the print statements (or to plot the function values), so you can track down what is going on more easily.

Yes you are right!

I get information about data1 instead of data2 and data3.
I will try to test the function "FundValue(FundFieldName,PeriodsAgo,oErrorCode)" as you mentioned.
I need to read the Low, High and the Close of datastrams but do not find any "FundFieldName" associated to them (yet).
Sorry that I am such a beginner regarding EL, but I get error while compiling my code with "FundValue"!

------ Compiled with error(s): ------
Unknown Function

Does this work in MultiChart?

Thank you so much for your support!

ShahramTor,

the link was just supposed to be an example of how to tie a function to a datastream (more specifically the last example in the link shows you how to do it). I didn't mean that you should use the FundValue function, as it will not give you what you are looking for.

By the way you can show your appreciation for posts on futures.io by clicking the "Thanks" button next to a post.

Hi,

I am afraid that I can not figure out how to tie the function to different data-stream.
Would you pls give me some examples?

Best regards
