Lot size is how big your trade is. It decides how much money you gain or lose per pip of movement. Trade too big and one bad move can blow your risk limit. The right lot size keeps every trade inside your plan.
How position sizing works
First you decide how much money you are willing to risk, usually a small percentage of your account. Then you divide that risk by your stop loss distance and the value of each pip. The result is your lot size. Prop Pilot does the math for you in one step.
Why it matters for prop traders
Consistent position sizing is what keeps a prop account alive. When every trade risks the same small amount, one loss cannot end your challenge. Size each trade on purpose, not by guesswork.
