I'm slowly but surely getting it but i still need some suggestions please.
This code is meant to be run in exploration mode for ALL stocks and within a date range. It calculates the percentage of bars that meet certain criteria - in this case it's the open price - for the specified date range and outputs it to the AA window.
this is an example of the arrays
----------------------------------------------------------------------------------------
m = open > 18 < 18.5 1 0 1 1 1 0 1 1 0 1 0 0 0 1 1 0 1 1 0 0
raw total = cum(m) 1 1 2 3 4 4 5 6 6 7 7 7 7 8 9 9 10 11 11 11
bar in date range 0 0 0 0 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0
lastvalue (cum(barinrange)) 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9
true positives 0 0 0 0 1 0 1 1 0 1 0 0 0 0 0 0 0 0 0 0
-----------------------------------------------------------------------------------------
as you can see the true positives are the number of times the "m" criteria was met WITHIN the date range. in this case 4/9 = 44%.
the code does what is supposed to do for the INDIVIDUAL tickers in the database. but since AB loops the code from scratch for each ticker in the database, it does not output the TOTALS for ALL stocks, which is what i'm intersted in.
so what I need to do now is to sum the individual results to calculate the overall percentage.
I've tried temporarily outputting the result for each stock to the clipboard with ClipboardSet() and ClipboardGet() but it doesn't work. here's the code. any suggestions are appreciated!
m = Open > 18 && Open < 18.5;
rawtotal = LastValue(Cum(m));
barinrange = Status("barinrange");
totalinrange = LastValue(Cum(barinrange));
truepositives = 0;
for ( i = 0; i < BarCount; i++ ){
if ( barinrange[i] == 1 ){
truepositives[i] = m[i];
}
}
truepositives = LastValue(Cum(truepositives));
PPV = (truepositives/totalinrange) * 100;
// NEED HELP FOR THIS PART ///////////////////
// HOW CAN I TEMPORARILY KEEP THE RESULTS IN MEMORY
// SO THAT I CAN ADD THEM TO THE RESULTS OF THE NEXT TICKER?
temp = StrToNum( ClipboardGet()) + truepositives;
ClipboardSet(NumToStr(truepositives));
//////////////////////////////////////////////
Filter = m == 1;
AddColumn(Open, "open");
AddColumn(rawtotal, "Raw Total");
AddColumn(totalinrange, "Total Bars in Range");
AddColumn(truepositives, "True Positives for Ticker");
AddColumn(PPV, "PPV", 1.1);
AddColumn(temp, "Total True Positives");
