[amibroker] CMS Trailing Stop System in AFL

["rocou" <rocou@xxxxxxxxx>]

Dear Traders, 
 
may I please ask for your help - how do I have to program the 
following 
"trailing stop system" of my broker CMS in AFL, to backtest/optimize 
the "n pips" stop values ?
 
Thank you for your help in advance.
Kind regards
Robert
 
 
{Trailing Stop Loss}
TrStopLevel:=If(C=PREV, PREV, If(((Ref(C,-1)<PREV)
AND (C<PREV)), Min(PREV,C*(1+nPips)), If((Ref(C,-1)>PREV) 
AND (C>PREV), Max(PREV,C*(1-nPips)), If(C>PREV,C*(1-nPips),C*
(1+nPips)))));

{Signal Up and Down}
Up:= Cross(Close,TrStopLevel);
Down:= Cross(TrStopLevel,C);
 
{OpenBuy, CloseBuy, OpenSell, CloseSell}
OpenBuy:= Up and (eventCount('OpenBuy')= eventCount('CloseBuy'));
CloseBuy:= Down and (eventCount('OpenBuy')>eventCount('CloseBuy'));
OpenSell:=  Down and (eventCount('OpenSell')= eventCount
('CloseSell'));
CloseSell:=  Up and (eventCount('OpenSell')>eventCount('CloseSell'));
