Cancel the stop-limit order directly and use a market order instead. In a gap move, your limit order has been "skipped" by the price. Continuing to wait will only increase losses; a market order is the only way to preserve your remaining capital.

First, understand why your order wasn't filled
A stop-limit order is controlled by two prices:
- Stop Price: When the price reaches this level, the order is triggered.
- Limit Price: After triggering, the order is placed on the order book at this price (or better).
Reaching the stop price merely places the limit order onto the order book — it does not guarantee immediate execution. When the market gaps, the price may jump from above the trigger directly below your limit price (for a long stop), or from below the trigger directly above your limit price (for a short stop). Your limit order sits there, but the price never returns, so it remains unfilled.
Prerequisite: You have a stop-limit order that has been triggered but not filled, and the price has moved significantly away from your limit price.
Cancel or switch to market? Decide case by case
Case A: Price still near the limit price (gap < 1%)
You can cancel and then place a new stop-limit order with a wider "safety gap" between the limit price and the stop price. According to Binance's official documentation, for a sell stop order, the stop price should be slightly higher than the limit price; for a buy stop order, the stop price should be slightly lower than the limit price. The larger the gap, the lower the probability of the order being "skipped" during a gap.
Case B: Price has gapped far beyond the limit price (gap > 1%-2%)
Cancel and then place a stop market order. A stop market order executes immediately at the current market price once triggered. Although it may slip, it guarantees execution. When the price continues moving against you, a stop market order is the only way to exit in time.
Tip: Binance's stop market order supports setting a "slippage tolerance" (0.1%-5%), which helps control how far the executed price can deviate.
Decide quickly — don't wait for the price to come back
The most dangerous move after a gap is to "wait and see." The stop being triggered means the market has confirmed its direction. Waiting for the price to return usually means waiting for losses to grow. An unfilled limit order is not a system issue — it's the market that has already moved on.
Risk reminder: A stop market order does not guarantee the execution price. In extreme market conditions, slippage can be severe. However, slippage only costs you a bit more; waiting for a limit order to fill may cost you your entire position.

Common reasons for failure
"Limit price set too tight": The limit price and stop price are too close, so in a gap the market jumps right over the pair without any chance of filling. Set the distance appropriately to give the order a "safe buffer zone."
After making the above decisions, how to confirm you're on the right track?
After canceling, check the current order book and latest trade price for that token — if the latest price is already far below your stop limit price, it means you've canceled an order that was already ineffective. Once the market order fills, your position is closed and losses are contained. If you're still hesitating, ask yourself if you can accept the current floating loss plus another 10%. If not, exit with a market order immediately.
