This guide explains how to complete a spot buy or sell order on Pionex, covering both the web version and mobile app.
Web Version
Step 1 Go to the Spot Trading Page
Click "Spot" in the top navigation bar to expand the dropdown menu.
Select "Spot Trading" from the dropdown to enter the trading page.
※ The menu also contains "Spot Bot", "MEME Master", and "Convert". Make sure you select "Spot Trading".
Step 2 Select a Trading Pair
After entering the page, the current trading pair is shown in the top left corner (① default is BTC/USDT). If you want to change it, continue to the next step.
Type a coin name such as ETH or SOL into the search bar at the top of the left panel (②).
Click the target trading pair from the list (③). The candlestick chart and order book will update in real time.
Step 3 Set the Order Type
Confirm that the right panel is showing the "Spot Trading" tab (④).
Select an order type (⑤):
Market (Smart) Executes immediately at the best available market price. No price input required.
Limit Set a target price manually. The order executes only when the market reaches that price.
Grid Buy Places orders across multiple price levels to average your entry cost. The minimum number of grids is 2, and the maximum number of grids is 50.
TP/SL Sets a "Rise to" take-profit trigger and/or a "Fall to" stop-loss trigger. Each trigger has its own execution price, which you can set to Market or Limit, and you can enable either side or both.
Step 4 Enter the Amount
Click the currency dropdown on the right side of the amount field (⑥) to select a quote currency (e.g. USDT).
Enter the amount or quantity you want to buy in the amount field (⑦). You can also use the 25% / 50% / 75% / 100% quick buttons to fill in a proportion of your available balance.
※ Make sure your available balance is sufficient. Insufficient balance will prevent the order from being filled.
Step 5 Review and Submit
Confirm that "Slippage Control" is checked (⑧). The system uses an AI-recommended value by default and does not need to be adjusted in most cases.
Once all settings are confirmed, click "Buy BTC" (or "Sell") to submit the order.
After submission, you can check the order status under "Orders" in the top navigation bar.

On the trading page, tap the "Spot" tab in the top right corner (①).
Step 2 Select a Trading Pair
Tap the trading pair name in the top left corner (②, e.g. BTC/USDT) to open the selection menu.

After submission, you can check the order status under "Open Orders" at the bottom of the page.
FAQ
Q: Does Spot Trading support leverage, or Futures-style Conditional orders?
A: No leverage. Spot's TP/SL and Futures' Conditional orders both place an order automatically once a trigger price is hit — the difference is what they act on: Spot TP/SL works on assets you already hold and places a new buy/sell order when triggered, with no leverage and no liquidation; Futures Conditional orders work on an existing leveraged position and close/reduce it when triggered (using Last Price or Mark Price), which carries liquidation risk. To trade with leverage or manage a position with a Conditional order, use Futures Trading.
Q: Can a filled spot order be cancelled or restored?
A: No. Once an order has been filled, it cannot be cancelled or restored. Please double-check the trading pair, order type, price and amount before submitting an order.
Q: Can I get a confirmation prompt before a spot order is placed?
A: Yes.
App: On the Spot Trading page, tap the「⋯」icon in the upper-right corner, go to Trading Preferences, and enable Order Confirmation.
Web: On the Spot Trading page, click the slider icon (Settings/Preferences) in the upper-right corner. Expand the menu and enable Order Confirmation.
Once enabled: A confirmation window will appear before each order is submitted, allowing you to review and confirm the order before proceeding.
Q: Can I set different quantity ratios for take-profit and stop-loss in Spot TP/SL? Why can’t I place a take-profit order after setting a stop-loss?
A: Not at the moment. When you set both take-profit and stop-loss in a single TP/SL setup, they share the same order quantity, and you cannot set different ratios for each. If you want take-profit and stop-loss to use different quantities, place them as two separate orders. For example, set only a stop-loss first with part of your holdings (such as 50%), then place another order with only a take-profit using the remaining holdings. The two orders are independent, and each is checked against your available balance at the time you place it. If you set the first order to 100%, the second order cannot be placed because your available balance is insufficient.
Q: Why is my limit order’s fill price different from the price I set? Is it a system error?
A: No, this is normal order matching, not a system error. A limit order fills at your order price or better: a buy never fills above the price you set, and a sell never fills below it.
If the market is already more favorable than your price when you place the order, the order does not wait at your price. It fills immediately at the better price in the order book, and the proceeds are calculated at the actual fill price.
Q: Can the price field remember the price I entered last time when I place several limit orders in a row?
A: If you do not want to type a price every time, you can use BBO (Best Bid and Offer) limit mode, where the system sets the limit price automatically from the live order book. The price is determined by the order book, not carried over from your last entry. See the BBO order mode article, available options depend on what the trading interface shows, and MEME tokens do not currently support BBO for limit orders.
Q: Can I use keyboard shortcuts to place orders on the web version?
A: Keyboard shortcuts for placing orders are not currently supported on the web version, for either Spot or Futures trading. Please set the order type, price, and quantity in the right-hand panel of the trading page, then click "Buy" or "Sell" to submit the order.
