I’m need help how the code is for calling values from an indicator. The indicator is made by Thomas on this forum(thanks for sharing!) and i want to use the return of mytdaylow, mytdayhigh and mytdaycenter in my trading system but I don’t understand how too call it.

Return mydayhigh COLOURED (255, 0, 0)style(line, 2) AS "High", mydaylow COLOURED (0, 255, 0)style(line, 2) AS "Low", mytdayhigh COLOURED (0, 255, 0)style(dottedline, 4) AS "Today High", mytdaylow COLOURED (255, 0, 0)style(dottedline, 4) AS "Today Low", mytdaycenter COLOURED (255,153,0,255)style(dottedline, 4)as "Today Centerline"

Return mydayhigh COLOURED (255, 0, 0)style(line, 2) AS "High", mydaylow COLOURED (0, 255, 0)style(line, 2) AS "Low", mytdayhigh COLOURED (0, 255, 0)style(dottedline, 4) AS "Today High", mytdaylow COLOURED (255, 0, 0)style(dottedline, 4) AS "Today Low", mytdaycenter COLOURED (255,153,0,255)style(dottedline, 4)as "Today Centerline"

The syntax for CALL is:

myValue1, myValue2, myValue3 = CALL "myIndicator"[parameter1,parameter2]

1	myValue1, myValue2, myValue3 = CALL "myIndicator"[parameter1,parameter2]

where myvalue are the returned values and parameter is the variables required by the indicator (so for example a period or setting).

So for your indicator replace myValue1 etc with your returned names and replace parameters with any that your indicator needs.

If a value is not used in your strategy then just replace its name with ‘ignored’.

If there are any parameters that you have to set or can modify in the indicator window after it is applied to a chart then these are the parameters.

I want the closing price (close) for each (day high, day low and day center) (5min) is that what I should put as a parameter or how do I write too get it?

I found some time to try to get CALL to work with that indicator but I couldn’t. There are no parameters needed but even if I created one by // out the lookback = 1 and creating lookback as a changeable parameter it still gives an error message.

The following strategy should just call the indicator (named MyIndicator(13) in my case) and draw the same lines on the chart but it gives the attached error.

ignored,ignored,mytdayhigh,mytdaylow,mytdaycenter = CALL "MyIndicator(13)"[1]

buy 1 contract at -high limit

graphonprice mytdayhigh 
graphonprice mytdaylow 
graphonprice mytdaycenter

ignored,ignored,mytdayhigh,mytdaylow,mytdaycenter = CALL "MyIndicator(13)"[1]

buy 1 contract at -high limit

graphonprice mytdayhigh

graphonprice mytdaylow

graphonprice mytdaycenter

I tested the same on a different indicator and it worked just fine so there is something about this indicator that it does not like.

You could just hard code the indicator into your strategy rather than use CALL while we all work out what is wrong.

From a quick scan through of the code it seems that the values that you want are just the daily high and daily low and a mid point between them which you can simply get by adding the following to your strategy:

mytdayhigh=DHigh(0)
mytdaylow=DLow(0)
mytdaycentre = (mytdayhigh-mytdaylow)/2+mytdaylow

mytdayhigh=DHigh(0)

mytdaylow=DLow(0)

mytdaycentre = (mytdayhigh-mytdaylow)/2+mytdaylow

Ok, I get the same error message when I run the program. It should work if we identify the problem. Thanks for the help and we keep in touch if we find a solotion.

Just add (Close) at the end of the CALL instruction and it should work.

So the correct format is (change indicator name to whatever you have it named as):

ignored,ignored,mytdayhigh,mytdaylow,mytdaycenter = CALL "MyIndicator"(close)

1	ignored,ignored,mytdayhigh,mytdaylow,mytdaycenter = CALL "MyIndicator"(close)

This deals with the required customclose that the indicator needs. I’ve had this issue before (this time I was putting the close in the [ ] which is why I could not get it to work!) Maybe the documentation for CALL needs a little update to cover this issue?
