#OrderTypes101 They give price control but may not execute if the market doesn’t hit your price. Stop orders trigger a market order when a stock hits a set price, often used to limit losses (stop-loss) or lock in profits. For example, a stop-loss at $50 sells if the stock drops to that level. Stop-limit orders combine stop and limit, triggering a limit order instead, but execution isn’t guaranteed. Day orders expire if not filled by the market’s close, while good-till-canceled (GTC) orders stay active until executed or canceled. More advanced types, like all-or-none (AON) or fill-or-kill (FOK), impose strict conditions on execution.
