output H L O C data issues....

[tulanch]

I have a rather extensive indicator that uses H L O C data in it's calculations.

It is a multi dataframe indicator. ( for example 5min and 10min) It also runs so that all trades are processed by the code (Calculate on bar close = False)

The graphing/ plotting is working perfectly.

I have placed a print statement in the main bar area to output Time, H L O C and my calculation value (that is plotted in the subpayne). The Time value and the calculation values are correctly printed, but the H L O C data contains a single value for all H L O C values on each output line in the output window. It makes no sense what value is being reported back for the H L O C values, each line is different form the previous, but all the H L O C values are the same.

Any ideas as to why this would occur? Any ideas on how to debug or resolve this?

I am confident I am referenceing the H L O C data correctly as the graph plotted and the calcuation value derived in this indicator are as I expect based on the H L O C values of the corresponding candle stick bars of the chart.

Hello tulanch,

Sorry, I'm not sure from the description what your script may be doing. If you can post a simplified portion we can take a look here.

I did a couple of things and now it's working....

First I did a database repair for the hell of it, I've seen that fix strange things in the past....

next, to me the problem looked like it was initialization related, sort of chicken before the egg problem.... having the indicator with CalculateOnBarClose = false and making use of FirstTickOfBar , it made me think to move the printout logic from the first few lines of the indicator's onbarupdate method to the end of this method in an effort to allow the system to properly initialize on a new bar.

I also got to thinking that using FirstTickOfBar with CalcuateOnBarClose=true may be the problem, so I added appropriate logic ... if CalculateOnBarClose is true, it no longer uses a FirstTickOfBar check but does use [0] indexes for Time, H L O C and the indicator data value. If CalcuateOnBarClose is false, it uses [1] indexes for data values within a OnFirstTickOfBar check.

I'm not certain when things cleaned up... but it's working as expected now.

I have a suspision I was using CalcuateOnBarClose = false (process every tic) using [0] indexes within an OnFirstTickOfBar check... this would explain why I had seemingly randon values as it would print out that ticks values, which most likely were always equal to each other.

thanks for letting me think out loud
