Instrument ### Trade Account balance USD Risk per trade % Entry price Market reference unavailable, type the entry Stop-loss price Position size you should take Enter balance, risk %, entry and stop to size the trade. How it works `risk amount = balance x risk %` `size = risk amount / (value per pip per lot x stop distance in pips)` The result is then rounded down to the smallest increment your broker actually accepts, so the size you are given always risks a little less than your limit and never more. A worked example 1. Balance $10,000, risking 1%, so $100 is on the line. 2. Long EURUSD from 1.0850 with the stop at 1.0800, a 50 pip stop. 3. One standard lot of EURUSD moves $10 per pip, so 50 pips costs $500 per lot. 4. $100 / $500 = 0.20 lots. FAQ ## Worth knowing ### What risk percentage should I use? Most traders working with a fixed-percentage model land between 0.5% and 2% of the account on any one trade. The number matters less than holding it steady. Sizing by feel is what turns one bad trade into a bad month. ### Does this work for futures, indices and crypto as well as forex? Yes. Pick the instrument at the top of the calculator and the contract specification comes with it, so a NASDAQ future is sized on its tick value and Bitcoin on its unit value rather than on a pip. ### Why is my size rounded down? Because your broker only accepts certain increments. Rounding up would quietly put more at risk than you asked for, so the calculator always rounds down and shows you the risk the rounded size actually carries. ### Where do costs come in? Add your round-trip commission per lot and it is taken out of the risk budget before the size is worked out, which is why a costed size is slightly smaller than a free one. ## The calculation is the easy half Connect your broker once and Edge learns from your trades, journal and practice to show you what to fix, sizing included.
