1)Market Order
Market Order is an order to buy or sell a security immediately without setting a price limit.
Note: Market orders can help clients execute trades as soon as possible. Market orders do not guarantee the transaction price, especially when the market changes rapidly, or for inactive contracts, market orders could be executed at a much higher or lower price.
2)Limit order
Limit order is an order to buy or sell a security at a specific price or better.
3)Stop-loss order
Stop-loss order is an order to buy or sell a stock once the price of the stock reaches the specified price, known as the stop price. When the stop price is reached, a stop order becomes a market order.
4)Stop-limit order
Stop-limit orders are a conditional trade that combine the features of a stop loss with those of a limit order to mitigate risk.
Stop-limit orders enable traders to have precise control over when the order should be filled, but they are not guaranteed to be executed.
