I assume you are telling us that your IIf statement is not working.
ApplyStop is "built-in" to the backtester. I don't think you can put it
inside a conditional statement. It "triggers" when the internal back
test procedure runs due to having Buy = Condition, Sell = Condition,
etc. //I am ready to be corrected on the above :-)
BuyPrice does not remember anything. It is merely a way to tell
Amibroker if you are buying at the Close or the Open (or some other
value) which changes on every bar. To tell AB to use the open price of
the NEXT bar, you must use these two lines of code:
BuyPrice = Open;
SetTradeDelays(1,1,1,1); //Sets Buy,Sell,Short,Cover delays
Of course, you will also want to set SellPrice, ShortPrice and
CoverPrice and set the TradeDelays appropriately.
If you want to remember the BuyPrice you must either keep a tracking
array using a loop or use ValueWhen(Buy,BuyPrice,1); which will give you
the BuyPrice of the most recent Buy signal...without regard to any
subsequent Sell, Short, Cover signals. If you have duplicate Buy
signals, then this gives only the most recent one, which may not be the
one you actually bought on.

Sorry. I mistyped my code! The correct code is this:
TradeStart = 1060505
Buy = DateNum()==TradeStart;
Sell = 0;
ApplyStop(stopTypeLoss,stopModePercent,3,1,0,1);
IIf(C > BuyPrice*1.02,ApplyStop
(stopTypeTrailing,stopModePercent,0.5,1,1,1),0);
I'm a very beginner and the above code is only an attempt to write a
micro trading system that help me to comprehend how AFL works. All
the code is written above.
Buyprice variable seems not to save the value of my enter the trade
in the date specified by TradeStart (5 May 2006). I don't know which
value Buyprice represents.
Thanks in advance for every suggestion.
