Do I have to open more than 1 chart to run my expert?
Magic number only allows an EA to identify its trades from all others. Using OrdersTotal/OrdersHistoryTotal (MT4) or PositionsTotal (MT5), directly and/or no Magic number/symbol filtering on your OrderSelect / Position select loop means your code is incompatible with every EA (including itself on other charts and manual trading.)
Symbol Doesn't equal Ordersymbol when another currency is added to another seperate chart . - MQL4 programming forum (2013)

You need one Magic Number for each symbol/timeframe/strategy. Trade current timeframe, one strategy, and filter by symbol requires one MN.
