If you use limit orders you add liquidity to the market.
Here's an example of the PrimeBit order book.
Choose "SELL", then choose "Limit" order type, set the "Quantity" (number of PrimeBit contracts), and activation price, which will be in our case 8738.5 (the lowest value on the sell-side in the order book) or higher. Double-check the order details and press the "SELL" button at the bottom of the order modal.
The order is now visible in the "Pending Orders" tab.
