Thanks

U should check the buffer value. To change the line color u need to have 2 buffers lets say that buffer 1 is blue buffer 2 is red.

Buffer 1 is defined as buffer 0 in init function, and buffer 2 is defined as buffer 1 in init SetIndexBuffer(0,buffer1);

So the first buffer covers second, if the first buffer will be empty - u will see the other color.

HI,

Just wondering how can I write this in EA that if the line is BLUE then BUY and if the line changes its colour from BLUE to RED then SELL...

babarmughal,

I've noticed that the TriggerLines indicator has 4 buffers!

1- when the color is BLUEthe 4 of them have values!

2- whenthe color is REDthe buffers 0 and 1 only have values!

So the code of the EA should be something like that:doublesignal = iCustom(NULL,0,"triggerlines",Rperiod,LSMA_Period,2,0);

if (signal != EMPTY_VALUE) <--- Color isBLUE

if (signal == EMPTY_VALUE) <--- Color isREDGive it a try!

Hi CG,

Thanks

You have to use code like this:

bool isNewSymbol(string current_symbol)

{

//loop through all the opened order and compare the symbols

int total = OrdersTotal();

for(int cnt = 0 ; cnt < total ; cnt++)

{

OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);

string selected_symbol = OrderSymbol();

if (current_symbol == selected_symbol && OrderMagicNumber()==MagicNumber)

return (False);

}

return (True);

}

if(OrdersTotal() < 1 || isNewSymbol(Symbol()))

{

if(BuyCondition) //<-- BUY condition

{

//<-- Open BUY order

return(0);

}

if(SellCondition) //<-- SELL condition

{

//<-- Open SELL order

return(0);

}

return(0);

}
