Position Size Calculator

How position sizing works

Professional traders decide how much they are willing to lose before they think about profit. This calculator turns that rule into a concrete position size.

• Amount at stake = account balance × the percent you set.
• Position size = that amount ÷ distance between entry and stop-loss.
• Trade value = that size × the entry price.

Capping losses at 1–2% per trade means a bad streak can't wipe out your account — so you can follow calls calmly and stay in the game.

A worked example

Say your account holds $5,000 and you cap losses at 1%, so you are willing to lose $50 on this trade. You enter at $60,000 with a protective exit at $58,800, a gap of $1,200. Divide the $50 you can lose by that $1,200 gap and you get about 0.0417 coins, worth roughly $2,500 at entry.

If price falls to your exit, the hit is close to the $50 you planned — no nasty surprise. Widen the gap and the same rule hands you a smaller stake; tighten it and the stake grows. The maths quietly keeps every bet in proportion.

Try it with a real setup from a call you are watching. Drop in the balance you trade, the slice you are happy to lose, and the two prices from the alert. The figure it returns is the most you should buy. Note it down, place the order, and move on to the next idea without second-guessing yourself.
