Position size & liquidation calculator

Work out how much to risk, how large a position that risk buys, and roughly where an isolated-margin position would be liquidated — before you place the trade.

Varies by exchange and position tier — check your exchange's margin tiers for the exact number. The default shown is a common lowest-tier value.

Approximate — real exchanges use tiered maintenance margin brackets that change with position size. Treat this as a rough guide, not an exact number.

AlgoVesta sizes trades the same way

When a bot's risk mode is set to Risk %, AlgoVesta computes position size from your balance, risk percentage and stop-loss distance — the same math as this calculator — before it sends the order.

The most common questions before you decide — if you still have doubts, start here.

It's the share of your account balance you're willing to lose if the stop-loss is hit on this one trade — commonly 0.5–2% for active trading. The calculator turns that percentage, together with your stop-loss distance, into a position size.
Margin is the collateral you lock up; position size (notional) is the full value you control. With leverage L, margin = position size ÷ L. A $500 position at 10x leverage only ties up $50 of margin.
If the exchange force-closes your position at the liquidation price before price reaches your stop-loss, you lose your entire margin instead of the smaller, planned stop-loss amount — your stop order never gets the chance to fill.
Yes. When a bot's risk mode is set to Risk %, AlgoVesta sizes the position from your balance, risk percentage and the distance between entry and stop-loss — the same approach used above.
