ADX error

[ScottMcNab]

Spent an hour or so trying to work out why system not taking codes in a couple of stocks that it should have…after some plotting and use of interpretation window i found the error is somehow in the adx calculation…on 99% of stocks the adx calc works fine as in the first image for GNW but occassionally it does not as in the case of CDR..it is the same code just run on 2 different stocks…hard to see how adx(7)>30 can be coding error… any thoughts greatly appreciated…thinking may have to upgrade amibroker version

adx calculated no problem for GNW…..but for CDR it goes beserk and returns -1.#J

adx graph for the stock CDR all good so don’t think database issue

Made a simple afl file to test

var1 = ADX(7);
“”;
“ADX7: “+NumToStr(ADX(7),1.3);
“”;
Plot(var1, “ADX7”, ParamColor( “Color”, colorRed ), ParamStyle(“Style”) );

adx plots fine and interpretn windows work so it must be some conflict in my backtesting and exploration code

ADX calculated correctly and CDR now appears in exploration if I remove the line

//SetBarsRequired(sbrAll,0);
getting somewhere…just not sure where

edit:
SetBarsRequired(1000,0); also works fine

Interesting, I also have
SetBarsRequired(sbrAll,0);
preceding all of my code.

Any idea on the reason? I will remove and test.

Not sure why in the CBT code Seth..above my pay grade…would have not know was causing error with ADX calc if someone else with differnt version of Ami was not trading the same system…every few weeks was a single discrepancy between trades in exploration…sbrAll works fine with that (latest) version of Ami
