Time Based Order Placer
Some trades are planned well ahead of when they need to be sent - a session open, a scheduled news release, a level that only matters at a specific moment. This EA arms itself with one target date and time, waits, and sends exactly one order at that instant: market or pending, buy or sell, with the usual stop loss, take profit and position sizing options shared across this catalogue. A missed-window guard keeps it from firing hours late. If the target time has already passed by more than InpMissedWindowSeconds by the time the EA next receives a tick - the platform was closed, the chart was frozen, the terminal just started - it logs the miss and disarms instead of sending a now-stale order into whatever the market happens to be doing when it finally wakes up. Position sizing, when risk-based, is built from the broker's tick value and tick size rather than a hardcoded contract size, so it prices correctly on gold, indices and JPY crosses as well as plain FX pairs. Notes and limitations - Fires once per EA attachment. Reattaching the EA (or changing an input, which reruns OnInit) re-arms it for the same InpTargetTime. - Server time, not local or broker's advertised timezone label - check the terminal's clock against the intended event before relying on it. - No news feed or economic calendar is read; the time is whatever is typed in, so it is only as accurate as the trader's own planning. - If risk sizing produces a lot size of zero for the given stop distance, the order is skipped rather than sent at an unintended size. - MQL5, netting accounts only: refuses to place the order if a foreign-magic position already sits on the chart symbol at send time, to avoid a silent merge. This check is only made once, at the scheduled moment - it is not re-checked later if a pending order triggers well after a foreign position has since been opened.
