Indicator not sending value to EA

 

I'm trying to develop a simple indicator that tells me the difference between 2 similar products eg. UK & US Oil. The indicator correctly displays variance on a chart but does not send the same value to my EA.

Any help would be appreciated.

extern int spread_distance_x = 10;
extern int spread_distance_y = 130;
extern bool normalize = false; //If true then the spread is normalized to traditional pips

double Poin;

double divider = 1;

Hi,

So you didnt implement a buffer for it,you should define a buffer,then spend the variance value into the buffer,or you could do it via global variables.

Or you could do this formula directly into your EA:

double spread = (MarketInfo("XBRUSD",MODE_ASK) - MarketInfo("XTIUSD",MODE_BID)) / Point/divider;

I put the code as suggested into the EA & disabled the indicator. EA now works fine.  Many thanks Mehrdad.
