Hi Edward,
You can keep track of your daily gain and when that 
  reaches your 
threshold block your buy and short signals. For instance you 
  might 
use buyPrice and sell price to calculate gain / trade that keep gain 
  
in its own array or static var, I prefer the latter, and just bump 
the 
  gain each time a trade is complete. 
buy = buyCondition and gain < 
  threshold.
This way the back tester never sees the additional or 
  potential 
trades and will give you better results. Also in back testing if 
  you 
use buyPrice, etc., if you are using conditions that occur mid bar, 
  
such as MA cross, then the back tester gives more accurate results. I 
  
had to use explore and dump that to excel to finally get the back 
  
tester to give correct results. Using close of the bar give incorrect 
  
results.

  the 
intraday profit / loss curve is shown. I guess I could put this data 
  
in a composite and use the compositie during a more detailed 
backtest. 
  Still the coding is pretty difficult since when the daily 
profit is 
  achieved you want the backtest to continue for the next day 
of intraday 
  data.

  day, if not 
take the profit/loss value at the close and just add these 
  value. Not 
so easy to program or have I been drinking too much liquor 
  lately?
