History Pool Types Decoder
OrderType() in the history pool is not "buy or sell" the way a lot of sample code treats it. Six real order-type codes (0-5: two market types plus four pending types) share the same pool as broker-generated balance and credit entries (6 and 7), which have no order side, no symbol and no lot size. A common "sum OrderProfit() over every history entry" loop silently counts a deposit or a bonus credit as if it were a winning trade, inflating the reported result with money that never came from trading at all. This script walks the pool once and classifies every entry independently: executed market trades (OP_BUY/OP_SELL), pending orders that reached history without ever filling (cancelled or expired - a triggered pending's type flips to OP_BUY/OP_SELL at fill time, so a pending code in history can only mean it never went live), balance operations (deposits/withdrawals) and credit operations (bonus/adjustments). Each category is totalled on its own, and the script prints both the blended total a naive loop would have reported and the correct trading-only figure side by side, so the size of the mistake is visible rather than asserted. Notes and limitations OrdersHistoryTotal() only covers whatever the terminal's Account History tab has currently loaded, not necessarily the account's entire lifetime history - this is a platform limitation, not something the script can see past. Codes 6 and 7 (balance and credit) are not documented MQL4 constants; they are the values MetaQuotes' own long-standing sample code has used for the platform's balance-tab operations. Any code value above 7 encountered on an unusual broker is reported as UNRECOGNISED rather than guessed at.
