Indicator does not show historical values

New comment
 

Hello.

The custom indicator that i've created does not show historical values on chart.

When i try to attach the indicator on any chart i can only see the values beginning from current bar. If i change the broker for some other company it works normal but if i change the symbols GBPUSD-GBPJPY to GBPJPY-GBPUSD, the problem occurs again.

Please help me.
