I've simplified the strategy so I can publish the script below. I made a few changes already and seems the TMF works better now. However, the TrailLock function remains a mystery to me - it simply doesnt execute at (in my case) 90% of the max profit of a trade. Do you have any advice for that too?

// ============== TRADER SCRIPT UPL, simplified for bug fixing ==============

int TMFLong()
{
Stop = priceLow(1)-Spread;
Trail = 2.9*ATR(1);

bool Cond_LongStop = priceHigh(0)<=priceHigh(1)<=priceHigh(2);

if(TradeResult>Trail) TrailLock = 90;

if(Cond_LongStop and TradeResult>Trail){
// exitLong();
return 1;
}

return 0;
}

int TMFShort()
{
Stop = priceHigh(1)+Spread;
Trail = 2.9*ATR(1);

bool Cond_ShortStop = priceLow(0)>=priceLow(1)>=priceLow(2);

if(TradeResult>Trail) TrailLock = 90;

if(Cond_ShortStop and TradeResult>Trail){
// exitShort();
return 1;
}

return 0;
}
