Link to this calculation- Risk : reward (after fees)
- Position size
- Position value
- Loss if stopped out
- Profit at take-profit
- Break-even win rate
- Stop distance
- Target distance
- Max leverage (liquidation beyond the stop)
- Leverage needed with the whole balance as margin
- Margin at your leverage
- Estimated liquidation price
The estimated liquidation price comes before your stop, so you would be liquidated first. Lower the leverage below the max leverage.
The margin needed is more than your balance. Use more leverage or a smaller position.
The fees are bigger than the move to your take-profit: this trade loses money even if the target is hit.
Estimate: These are estimates. Exchanges use tiered maintenance margin (bigger positions need more), liquidate on the mark price rather than the last trade, and handle fees and cross margin their own way. Check your exchange's position screen before you trade.
Worked example
BTC long, the numbers above- Each BTC loses $1,695.60 between entry $84,777.50 and stop $83,081.90, and makes $3,391.10 between the entry and the take-profit at $88,168.60 (plus 0.05% fees on each leg).
- Reward ÷ risk after fees = $3,304.63 ÷ $1,779.53 = 1.86, written 1 : 1.86. You break even if more than 35.00% of trades like this hit the target.
- Risking 1.00% of $10,000.00 = $100.00 gives a position of $100.00 ÷ $1,779.53 = 0.0561946 BTC ($4,764.04). At the take-profit it makes $185.70.
- The liquidation price must stay beyond the stop, or the exchange closes you out first. With a 0.33% maintenance margin rate that holds up to 42.2x. The position is worth less than your balance, so it needs no leverage at all (0.476x with the whole balance as margin).
The formula
Risk per coin = |Entry − Stop| + fee × (Entry + Stop) · Reward per coin = |Target − Entry| − fee × (Entry + Target)
R:R = Reward ÷ Risk · Break-even win rate = 1 ÷ (1 + R:R) · Position size = Balance × Risk % ÷ Risk per coin
Max leverage (long) = Entry ÷ (Entry − Stop × (1 − MMR − fee)) · (short) = Entry ÷ (Stop × (1 + MMR + fee) − Entry)
The max leverage is the liquidation price formula solved for the leverage that puts the liquidation price exactly on your stop. Above it you are liquidated before the stop fires. The size comes from the position size calculator's formula: the stop, not the leverage, sets what you lose.
