AA Global Position-Size Calculator
Pick your market, enter your account, risk and stop distance, get the exact lot size, rounded to what Deriv actually accepts. Every spec is taken from live Deriv MT5 contract specifications.
Why each market is different
Every symbol has its own contract maths: how many dollars one unit of movement is worth per lot, the minimum lot Deriv accepts, and the step lots must move in. A stop of 100 on Volatility 75 risks a hundred times less per lot than the same stop on Volatility 75 (1s), same chart shape, completely different money. Boom and Crash won't let you trade below 0.2 lots, while V75 goes down to 0.001. That's why this tool asks which market first, and why guessing lot sizes across markets destroys accounts.
Forex pip values for USD-cross pairs (JPY, CHF, CAD) shift slightly with the live exchange rate; the figures here are close enough for safe position sizing. Always confirm against your own MT5 before a real trade.
