What's mark price vs last price vs index price?
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.Published on Apr 15, 2026Updated on Sep 4, 20261Why did I pay more than the market price?
