Automate the data (symbol, entry, exit, size, SL/TP, fees), write only the decisions (why you entered, how you felt, the takeaway). MT4/MT5 sync via an EA plus a sync token, cTrader and OANDA via read-only API with up to 5 years of history, crypto exchanges via read-only keys, everything else via CSV with automatic format detection.
