What is a stop order?
A stop order basically allows you to place a buy or sell order after the index price has touched a specific point, called a Stop Price or Trigger Price. When placing a stop order, you specify if you would like to buy/sell, and then provide an amount and a stop price. Once the index price touches your stop price, an order will automatically be placed to market buy/sell your order amount.
For stop orders placed with open positions, stop orders will automatically fully close your position, so you only need to provide a stop price.
What is the index price?
The index price is an aggregate price that uses multiple price oracles from different exchanges. Both liquidations and stop orders use this price to determine when your account needs to be liquidated or a stop order has been triggered. Using an index price like this protects you from unexpected execution in times of high volatility.

For open positions, your stop order will automatically fully close your position, so only one stop order is allowed per position. For trades placed on the " tab, there is no limit to the number of stop orders you can have for each market, as long as those orders can't potentially put your main account under the collateralization threshold.
Can I place stop orders on margin?
Yes - stop orders can be places on margin so long as you maintain a sufficient collateral ratio - 125%. If you have open stop orders and your collateral ratio falls below that threshold, orders will be cancelled based on distance to mid-market price (closest to mid market will be cancelled first). This is because orders further away from mid market impact your collateralization level less than orders closer to mid market.
