The Order Entry panel is where you place market orders or pending orders. To open the Order Entry panel select Main Menu > Order Entry.

Account - you can change the account if you want.
Instrument selects available instrument for trading.
Type - it can be Market, Limit, Stop, OCO, Stop Limit. A Market order guarantees execution, and it often has low commissions due to the minimal work brokers need to do. A Limit order placed with a brokerage to buy or sell a set number of shares at a specified price or better. A Stop order to buy or sell a security when its price surpasses a particular point, thus ensuring a greater probability of achieving a predetermined entry or exit price, limiting the investor's loss or locking in his or her profit. OCO is an order stipulating that if one part of the order is executed, then the other part is automatically canceled. A stop-limit order will be executed at a specified price (or better) after a given stop price has been reached. Once the stop price is reached, the stop-limit order becomes a limit order to buy (or sell) at the limit price or better.
TIF - Time-in-force options allow traders to be more specific about the time parameters in which an order is activated. This is especially important for active traders. It can be Day or GTC. A Day order, as the name implies, is valid for the current trading day. Good till canceled orders, on the other hand, will remain live until they are canceled.
Risks - you can set price for Stop Loss or/and for Take Profit. If you need you can use Set Trailing Stop. Using a Trailing Stop allows you to let profits run while cutting losses at the same time.
