Very Weird Problem Loading Historical Data: Error message " no history data 'EURGBP(£)1' " it works for all other period.

New comment
 

So I'm new with MT4 and for that matter to forex trading.

Today I was trying to do back testing with some EAs. What I've noticed that for some reason the back testing is not working if I use 1 minute period. It only works on 15 minute period. 

I tried to download historical data from in csv format [redacted] then done the basics which I found on this forum for example add to the history center. 

The weird thing is the back testing is possible on 15 minute , 30 minute etc but when I try 1 minute period - it throws error message

Have you checked your MT4 History Center to inspect the data?

A screenshot of that window would help us help you.

To clarify, that is a Tester log.

You need to inspect the M1 timeframe data for your symbol and backtest times chosen in the History Center.
