  1. Step 1: Choose Risk as the ticket’s size

    In the order ticket, open the unit beside Size and choose Risk. The ticket sizes in 3 ways, Money, Lots and Risk, and switching converts the value you typed. With Risk, type the amount of money you are willing to lose on this trade.

  2. Step 2: Set your stop loss

    Under Exits, set a Stop loss as a price, a distance in ticks or a percent. The stop loss is where your risk is measured, so without one the ticket cannot size by risk and tells you to set it.

  3. Step 3: Read the lots it works out

    Under Size, the ticket shows the lots it calculated and the margin they need, and the Buy or Sell button names the size. Est. loss shows what you would lose at the stop loss. Move the stop further away and the size gets smaller, so the risk stays the same.

  4. Step 4: Plan with the long or short position tool

    In the drawing tools, choose Long Position or Short Position and place it on the chart. Right-click it and choose Settings…. On Inputs, it reads your account size and leverage live from your account, works out the lot size from your risk, and shows the required margin, the free margin after the trade and whether you can afford it right now.
