How to get every last Bid price, fastest way

New comment
 

Hello!

 I would like to know how to get every last Bid price of EURUSD, GBPUSD and EURGBP on EURUSD chart.

For now I have: 

double EU1 = MarketInfo("EURUSD",MODE_BID);
double GU1 = MarketInfo("GBPUSD",MODE_BID);
double EG1 = MarketInfo("EURGBP",MODE_BID);

 

but I think this is faster:

double EU1 = Bid;
double GU1 = MarketInfo("GBPUSD",MODE_BID);
double EG1 = MarketInfo("EURGBP",MODE_BID);

 

Is with iClose faster? Like this:

 double EU1=iClose("EURUSD",PERIOD_H1,0);
 double GU1=iClose("GBPUSD",PERIOD_H1,0);
 double EG1=iClose("EURGBP",PERIOD_H1,0);

What do you think is the faster way when using for calculation? 

 
You are getting values over the network, taking tens or hundreds of milliseconds at best. The difference between those methods will be in nanoseconds. Irrelevant.
 
Thank you! Can you tell me how can I "run" indicator every second or all the time? Now it updates values only on tick change on chart where it is attached. And solution?
 
Why would you want to run it when nothing has changed?
 
Prices of other pairs may change and because of this calculations I need also.
 
Use this.
