Ok. I tried that, but I ran into a problem.
I tried to find the buy price based on the criteria.
Buy =
C > 5.0 AND
ROC(C,10) > 0 AND
PDI(10) > MDI(10) AND
ADX(10)>25 AND
C > EMA(C,10) AND
C > TrailStop AND
Open > TrailStop;
Buycriteriaprice = IIf(Buy = 1, C, 0);
The last line placed buy arrows for buys one after the other on the chart and in the backtest table. That didn't work.
I had defined TrailStop earlier too. That seemed okay.
I have not been able to find the way to obtain the buy price (closing price) for the day the buy is made and ignore immediately subsequent days when the criteria is met. That is, I don't want purchases of the same security for days in a row.
Can you help me with identifying and obtaining the buy price?
Thanks.
