The script executes BuyMkt and SellMkt orders with the Numpad7 and Numpad8 Hotkeys keystrokes.

A BuyMkt order is submitted when pressing the Numpad 7 key (while the mouse cursor is over the Chart Window and the Chart window is selected/active).
A SellMkt order is submitted when pressing the Numpad 8 key (while cursor is over the Chart Window and the Chart window is selected/active).

Just simply import the indicator: Control Center > Tools > Import > NinjaScript Add-On > locate "BuyMktSellMktHotkeys.zip"
Then load it on your chart: Right Click > Indicator or Ctrl+I > Available pane > Select "BuyMktSellMktHotkeys"
Then activate the numeric pad (press the Num Lock key)
Then press numpad7 key to enter a Market Long trade order, then press the numpad8 Key to close your long trade with a Market Sell order. Vice Versa for Short and Buy to cover trades.

Note about the size:

You can customize the size of your trades by hardcoding them in the script.
To change the size of your BuyMkt Order hotkey, simply change the number 1 in bold at line 125 in the script to whatever size of your choice:

buyMktOrder = myAccount.CreateOrder(Instrument, OrderAction.Buy, OrderType.Market, OrderEntry.Manual, TimeInForce.Day, 1, 0, 0, "", "buyMktOrder"+DateTime.Now.ToString(), DateTime.MaxValue, null);

Similarly, to change the size of your SellMkt Order hotkey, simply change the number 1 in bold at line 138 in the script to whatever size of your choice:

sellMktOrder = myAccount.CreateOrder(Instrument, OrderAction.Sell, OrderType.Market, OrderEntry.Manual, TimeInForce.Day, 1, 0, 0, "", "sellMktOrder"+DateTime.Now.ToString(), DateTime.MaxValue, null);
