Without looking at your code, add these statements at the top:
SetOption("MaxOpenPositions", numPos = Param("Max Open
Positions",15,5,50,1));
Fixed = Param("Amount to trade, 0 ",0,1000,50000,1000);
//Using 0 will auto compute % to trade based on Max# Positions
PositionSize = IIf(Fixed,Fixed,round(-100/numPos));
//Param("Position Size - see notes in
SetOptions.afl",-10,-100,1000000,1);
Check out SetOptions in HELP for more useful things to set.

Subject: [amibroker] Newbee System Programming - Need some Help...
/* For all of you who are more expert than I am I have finally
completed my first new system... However, it only selects 1 stock
with 100% winning ratio... The thing is, I am puzzeled because when
I look manually at a stock chart, I see these "requirements" being
met several times over. I expect many buy and sell and short and
cover signals, but that isn't what I am getting. If someone would be
kind enough to run this code, look at it, and perhaps help me
understand why it is not working as expected, I would appreciate the
help! thank you! */
