Stop order

Petr’s instruction waits until its price condition is met. Once triggered, a common Stop order becomes a Market order and seeks available counterparties. Investor.gov explains this mechanism for stocks; Kraken describes it for its cryptocurrency stop loss orders too. A trigger notification therefore says it is time to start executing the instruction. It does not by itself confirm that the whole quantity has sold or at what price. [1] [2]

A sell stop is usually placed below the current price to respond to a fall. A buy stop above it waits for a rise. Investor.gov distinguishes these directions. Kraken also explains that a stop can be used to enter a trade, not just end one. The name alone therefore does not tell you whether you are buying, selling, entering or exiting. That depends on the chosen direction and what you already hold. [1] [2]

Petr may see the threshold crossed on another website while his order is still waiting. The price source may be different. Kraken distinguishes the last traded price from an index, a calculated price measure available as a trigger on supported pairs. The order’s configured reference matters, not an arbitrary chart. The direction matters too: Kraken warns that placing the stop on the opposite side of the current price can trigger it immediately. [2]

After triggering, the buyers’ offers matter. If the price is falling quickly, or little buying interest is available nearby, Petr may sell below his threshold. FINRA warns about this risk for stock stop orders; a trigger is not a price guarantee there either. For a buy stop, the execution price can instead be higher. Assessing the result therefore requires actual fills, their quantities and fees. [3]

Imagine a sharp fall triggers Petr’s stop and his sale executes. Soon afterwards, the price recovers. FINRA describes this risk: a short-lived movement may be enough to trigger the order even if the market then settles. Recovery does not undo a completed trade. A stop order does not decide whether a movement is a lasting trend or a temporary swing; it evaluates its condition. [3]

A Stop-limit order creates a limit order when triggered: a sale can execute only at the limit or higher, a purchase at the limit or lower. Part or all of the order may therefore remain unfilled. For futures, contracts for future settlement, CME also describes a stop with a protective price range. It permits fills only within that range. These are particular market rules, not a feature of every bitcoin stop order. Price protection alone does not guarantee completion. [4]

Petr may change his plan and sell manually. He should not assume this removes every waiting stop. Kraken warns that a standalone stop loss is not automatically linked to a position and may need cancelling if that position is closed another way. The reduce-only option, where available and enabled, is intended to restrict the order to reducing a position. The actual setting matters. Checking open orders helps identify an old plan that has stayed active unnoticed. [2]

Before submission, understand the threshold, quantity and expiry. CME describes futures instructions that last only until the trading session ends, as well as orders left active until cancelled. Your own platform’s specific rules need checking. After triggering, Petr checks how much actually filled, at what prices and whether any remainder is still waiting. Those details establish the outcome; a label saying triggered does not replace them. [4]
