MetaTrader and order book

Ok, I must say the "Ask" and "Bid" predefined variables stores the actually best orders... But what about the other levels and lots of the order book? Can I use these data in my code anyway?

Please help me, I searched a lot everywhere on the web but didnt find the answer.

One Fast question...

Dude if i do the bolded so i dont need to do the underlined right?

if(Ask>=Line1)

{

posisi=OrderSend(Symbol(),OP_BUY,Lots,Ask,Slipage,0,0,"OneLineEA ver 1.0",Megic,0,Green);

if(OrderSelect(posisi,SELECT_BY_TICKET)==true)

{

posisi=OrderTicket();

}

}

 

Please help me

HI codersguru

Thanks a lot FOR YOU

PLEASE CAN YOU EXPLAIN THIS STATMENT AND THE meaning

for(int shift = Bars-10; shift >= 0; shift--)

{

ExtMapBuffer1[shift] = ma[shift];

ExtMapBuffer2[shift] = ma[shift];

//Print (ma[shift]);

if (ma[shift] > ma[shift+1])

{

ExtMapBuffer1[shift] = EMPTY_VALUE;

ExtMapBuffer2[shift+1] = ma[shift+1];

}

else if (ma[shift] < ma[shift+1])

{

ExtMapBuffer2[shift] = EMPTY_VALUE;

ExtMapBuffer1[shift+1] = ma[shift+1];

}

IN THIS EA

//---- indicator settings

thank you

 

It's not EA, it's the indicator, which show you moments when "Moving Average" indicator goes up or down.

That code you need calculates last ten bars only.

Put it in /indicators directory and restart your terminal.

 

the diffrent

hello all

can help me

what the diffrent EMA5c and EMA5p

what the mean (EMA5c>EMA10c && EMA5pEMA10c))

double EMA5c = iMA(NULL,TimeFrame,5,0,MODE_EMA,PRICE_CLOSE, 0);

double EMA10c = iMA(NULL,TimeFrame,10,0,MODE_EMA,PRICE_CLOSE,0);

double EMA5p = iMA(NULL,TimeFrame,5,0,MODE_EMA,PRICE_CLOSE, 1);

double EMA10p = iMA(NULL,TimeFrame,10,0,MODE_EMA,PRICE_CLOSE,1);

 

The names are just variable names and don't really have any meaning as such. Programmers will usually choose variable names so that it's self explanatory what kind of value they're supposed to hold. Looking at those two it seems the programmer has chosen to add the suffix c to the current bars variable and p to the previous bars variable.

hey man got a question, I have an indicator that a friend gave me that I have been demoing for a couple weeks now and love it. Short explanation, an arrow will show up on my charts telling me to which way to play the movement. Using it on 30m charts so it doesn't come up too often. Is there a way to make it when the arrow shows up for the long position it will close out my short position and go long, or if there is no short position just go long. Also vice versa with the short signal?

 

I didnt see an edit button so here is the code. It doesn't seem as if it would be too difficult just to add in the buy or sell code. This is from the zigzag code. Free ind.

Look in the metaeditor help file at the iCustom function.
