A TP/SL order triggers on the price type set as its trigger price. You choose that price type when you place the order — last price, mark price, or index price — and the order watches only the price type you chose, not the other two. Because the default chart is drawn on the last price, an order can look as though it should have triggered when the price type it actually watches did not reach your level. Check the trigger price type on the order before concluding that it failed.

What is a spot index price? Spot Index price aims to measure the price of an underlying cryptocurrency.

Following a sharp rise in its price beginning in early November 2024, the token experienced an initial sudden and substantial price decline of more than 80% across the market at approximately 2:28:32am (UTC+8) on April 14, 2025 ("Market Event"). We observed that substantial trading volume spikes and price decline initially happened across various centralised exchanges outside of OKX, before spreading to the overall market.

Future changes to the cost price resulting from spot trading will also be based on the edited cost price. For example: If your trading account holds 1 BTC with a cost price of 60,000, and you transfer another 1 BTC from your funding account, your trading account will now hold a total of 2 BTC. If you then edit the cost price to 61,000, the cost price of the 2 BTC in your trading account will be updated to 61,000.

A price difference loss refers to a loss caused by the difference between the mark price at 9:07:26am UTC (48.36 USDT) and the resulting liquidation prices during the period. For example: If 10 OKB was liquidated at a liquidation price of 40.0 USDT, OKX will compensate difference of (48.36 - 40.0) * 10 = 83.6 USDT. Compensation will also include the associated liquidation penalty and trading fees (as determined by OKX), and exclude any bankruptcy losses already covered by the insurance fund.

The bot will place the order at the limit price if the order price is higher than the predefined limit price. If the order amount is more than the predefined average amount, the bot will place the order based on the average amount* random ratio (0.5~1). The order will be suspended when the last price (20,500 USDT) is higher than the limit price and resumed when the last price is below 10,500 USDT again. The bot will stop when the total filled amount equals the total order amount.

On a pair with little activity the price can sit unchanged for hours, and the candlestick chart can show flat stretches or gaps where no trades occurred. This isn't a display fault. To check for yourself, look at the 24h volume and the order book. If volume is low and the book is thin, the chart is showing that there were no trades in those intervals.
