A small bug in the Full Settings/Data/Commission and Swap.
The program resets the swap and commission values if you change the symbol, even if you return to the initial symbol where the values were set.
A more detailed example.
1. The EURUSD symbol is set, I set the commission and swap. I conduct testing, etc.
2. Then I switch to GBPUSD, etc.
3. I switch back to EURUSD and there are zero values in the commission and swap field.
This is very inconvenient.
This is not a bug.
When you switch the symbol, the default swap/commission values from the instrument are set.
