I need a trailing stop function for the code below. I've checked out several trailing stop functions from metastocktools.com and also the Advanced trailing stop plugin. I am not able to integrate this as a working method for my code using a 5 min. chart forex.

For BUY
c1:=MACD();
c2:=Mov(MACD(),9,E);

LE:=Ref(Cross(c1,c2),-1) AND
C > Ref(C,-1) AND Stoch(12,3)<50;

Tr:=
If(PREV<=0,
If(Ref(LE,-1),O,0),
If(
(H-0.0020)>PREV OR
(L+0.0050)<PREV,-1,PREV)
);

Tr>0 AND Alert(Tr<>0,2)

-----------------------------
For SELL

c1:=MACD();

c2:=Mov(MACD(),9,E);

LE:=Ref(Cross(c1,c2),-1) AND
C > Ref(C,-1) AND Stoch(12,3)<50;

ATRstop:=ATR(10)*2;

Tr:=
If(PREV<=0,
If(Ref(LE,-1),O,0),
If(
(H-0.0020)>PREV OR
(L+0.0050)<PREV OR C<PREV-ATRstop
,-1,PREV));

Tr=-1;

You see, i've been trying something with ATRstop, but it actually doesn't make any sense (C<PREV-ATRstop)

I want a trailing stop that is activated when the first 20 pip pricetarget has been reached OR when a certain amount of timeperiods has passed. That trailing stop should be able to exit the trade when 15% decrease has taken place based on the highest value since the 20 pip pricetarget has been reached. Any help is welcome!

(ps. the buysignal still carries the problem that it keeps plotting buysignals even if the condition isn't true anymore...very weird. The reference to the entryprice for defining the exittarget is working fine though)

Thanks Wabbit, yes indeed deja vu, i'm still not finished with this code :-)

Nevertheless, this new topic concerns a new problem. The previous problems with referencing the openingprice so i could catch a 20 pip movement is solved.

Next problem is activating a trailing stoploss AFTER this 20 pip movement has evolved.
Your suggestion is therefore not suitable as i wish to cancel the 20 pip exitcriteria when the trailing stoploss is activated. In other words, the High doesn't have to be 20 pips higher for the trailing stoploss to be active later on....the 20 pips higher should only work as a trigger. So....the code below is wrong, but i'll try to explain:

c1:=MACD();
c2:=Mov(MACD(),9,E);

LE:=Ref(Cross(c1,c2),-1) AND
C > Ref(C,-1) AND Stoch(12,3)<50;

Tr:=
If(PREV<=0,If(Ref(LE,-1),O,0),
If(
(L+0.0050)<PREV OR (H-0.0050)>PREV OR
C<HighestSince(1,PREV<=0,H) {this must be active after PREV has a new value (prev=h) }
,-1,If(((H-0.0020)>PREV),PREV=H,PREV)));

Tr=-1;

I've added an extra if-statement that should look for a pipmove of 20, if the move is found i want the openingprice to change from the PREV value to the H value that contains the price with 20 pip move in it. So next time this is executed this line: C<HighestSince(1,PREV<=0,H)
that works as a trailing stoploss should have the last H value. But i've no idea how to code this. I hope this makes sense..

ps. right now my chart only represents one buy signal followed by an immediate sell signal because the trailing stoploss looks for the first highestbar, so this is the bar next to the buysignal.
