View Full Version : Initial stop coding error

Hi everyone this my first post here.
I have just recently bought Tradesim Pro so am on a very steep learning curve.
Would somebody mind having a look at the attached code for a STTC system that I am having trouble coding,
I want to enter the trade on the open the day after the trigger and bid up to 1/2*ATR(10) above trigger day close,my initial stop is Entry price minus 2*ATR(10) and trailing stop is a close below the lowest low in the last five days.
When I put my triggers, gates, stops etc into a Metastock explorer and click OK it has a problem with the LongInitialStop function,I get a meassage that says "This is not a recognised name,constant or operator" ???

LongInitialStop := LongentryPrice-Ref(2.5*ATR(10),-1);

The entire code is as follows

{=== SET DATE VARIABLES ===}
DayStart := 1; MthStart := 1; YearStart := 2001;
DayStop := 31; MthStop := 3; YearStop := 2004;

{=== LONG TRADES ===}

LE := C+0.5*ATR(10);

LongEntryTrigger :=
{T} H>Ref(H,-1)AND
{1}Ref(H,-1)>Ref(H,-2)AND
{2}Ref(H,-2)>Ref(H,-3)AND
{3}Mov(C,120,S)>Ref(Mov(C,120,S),-40)+4*ATR(80) AND
{4}C>0.5 AND
{5}ATR(30)/ C >0.015 AND
{6}Mov(V,21,S)* Mov(C,21,S)>150000 AND
{7}V>1 AND
{8}C>O AND


Ref(L,1)<=LE;

{LongEntryPrice -Ref(0.5*ATR(10),-1);}

LongExitTrigger:=
ExtFml("TradeSim.TrailingStop",TRIGGER,LONG,Ref(LLV(L,5),-1),HIGH,CLOSE);

LongExitPrice := OPEN;

LongInitialStop := LongentryPrice-Ref(2.5*ATR(10),-1);

ExtFml( "TradeSim.Initialize");
ExtFml( "TradeSim.SetStartRecordDate",DayStart,MthStart,YearStart);
ExtFml( "TradeSim.SetStopRecordDate",DayStop,MthStop,YearStop);
ExtFml( "TradeSim.EnableDelayOfEntryByOneBar");
ExtFml( "TradeSim.EnableDelayOfAllExitsByOneBar");
ExtFml( "TradeSim.EnableProtectiveStop",0);
ExtFml( "TradeSim.UseClosingPriceAsStopThreshold");
ExtFml( "TradeSim.EnableTradePyramiding",Trigger, 0, 200);
ExtFml( "TradeSim.RecordTrades",
"STTC BullmK1",LONG,LongEntryTrigger,LongEntryPrice,LongInitialS top,LongExitTrigger,LongExitPrice,START); { Recorder Control }



Thanks for any advice.

Thanks for your help Jose

I ran this code through Metastock Explorer opened the reports and in the Trades column every stock has N/A as though no trades where found???

GB, there are logical errors in your LongExitTrigger trailing stop.
Try this:


LongExitTrigger&#58;=ExtFml&#40;"TradeSim.TrailingStop",
TRIGGER, &#123;mode&#58; band or trigger&#125;
LONG, &#123;long or short&#125;
C-Ref&#40;LLV&#40;L,5&#41;,-1&#41;, &#123;trailing stop buffer&#125; &#123; <-- error here &#125;
HIGH, &#123;RefPoint for stop calc&#125;
CLOSE&#41;; &#123;threshold - stop breached&#125;


And rather than pile entry condition upon entry condition and hope for the best, it's always a good idea to test every component of a TradeSim exploration, by plotting it as a visual MetaStock indicator first.
For example:


LE&#58;=C+0.5*ATR&#40;10&#41;;
LongEntryTrigger&#58;=
&#123;T&#125; sum&#40;H>Ref&#40;H,-1&#41;,3&#41;=3
AND &#123;1&#125; Mov&#40;C,120,S&#41;>Ref&#40;Mov&#40;C,120,S&#41;,-40&#41;+4*ATR&#40;80&#41;
AND &#123;2&#125; C>0.5
AND &#123;3&#125; ATR&#40;30&#41;/C>0.015
AND &#123;4&#125; Mov&#40;V*C,21,S&#41;>150000
AND &#123;5&#125; C>O
AND &#123;6&#125; Ref&#40;L,1&#41;<=LE;

LongExitTrigger&#58;=ExtFml&#40;"TradeSim.TrailingStop",
TRIGGER, &#123;mode&#58; band or trigger&#125;
LONG, &#123;long or short&#125;
C-Ref&#40;LLV&#40;L,5&#41;,-1&#41;, &#123;trailing stop buffer&#125;
HIGH, &#123;RefPoint for stop calc&#125;
CLOSE&#41;; &#123;threshold - stop breached&#125;

&#123; Plot trigger signals in own window &#125;
LongEntryTrigger-LongExitTrigger


The indicator above plots very few entry signals - perhaps take another look at each of the entry conditions. Try switching some of them off, and plot signals to see result.

Sorry for the delayed response Ive been on nightshifts,thanks very much for your help Jose it has given me something to build on.

I havent had Tradesim for long and its taking a bit of getting use to.
