Reloading a chart/indicator programatically to determine dynamic trade parameter

Hi,

I still consider myself a novice NT7 developer, so maybe this is easier than I think, or maybe it can't be done at all.

I created an indicator that has 1 parameter or setting. This setting really determine how many signals the indicator will show. I have a private variable that counts the number of signals on my chart and plots the signal number along with an arrow, so if I change this parameter to 100 (lets call it minimum trade score) I will have HUNDREDS of signals on a historic 10 day chart. If I change minimum trade score to 500, I may only see 1 or 2 trades on the same 10 day historic chart. Usually I have to find a value somewhere in the middle of 100 and 500, like 350, that will produce 30 signals on a 10 day chart, and I accept this minimum trade score value for creating signals in real-time.

So would much rather have a parameter called something like "Max Signals" and set that value to 30, and when I apply that parameter to my indicator, the indicator behind the scenes would start with minimum trade score value of 100 and store all the signals and scores into an array. Then I would loop through the array and count the number of trades with an increase of increment of 25 to the minimum trade score (100, 125, 150.. up to 500), to find which minimum trade score will produce around 30 trades (or whatever the desired number of trades for the time range on the historic chart), lets lets say 325 is 37 trades, and 350 yields 28 trades. I then plot the minimum trade score of 350 on the chart for informational purposes and reload the chart using that setting, so the chart actually shows 28 signals (arrows). Is this possible?

I figured the only way to make this possible is to load the chart twice. Once to determine all the signals, and the 2nd time to show the chart with the desired number of signals.

Any help would be appreciated.

Thanks.. tom
