My trade was rejected — why couldn't I open the position?

The trading terminal rejects an order when a safety check fails. The most common reasons are:

• Market closed — you can't open a position on a venue that's shut (weekend forex/metals, after-hours stocks/indices). Protective exits (SL/TP/stop-out) still run 24/7; only opening is session-bound.
• Insufficient free margin — your available margin can't cover the position. The error shows exactly how much you need vs. have; deposit more or reduce your volume/leverage.
• Volume limits — below the symbol's minimum lot, above the platform max, or above your account/membership lot cap ("Volume exceeds account limit").
• Invalid Stop Loss / Take Profit — an SL/TP placed on the wrong side of the market (e.g. SL above price on a BUY) is rejected so it can't instantly trigger.
• No live price / feed unavailable — if the price feed is down or stale for that symbol, opening and manual closing are paused until it recovers.

For AI-agent investing (not the manual terminal), an invest can be rejected because the bot requires a higher membership tier ("This bot requires a higher membership tier"), the amount is below the plan's minimum, or your balance is insufficient.
