Fibonomy

Futures position size calculator

Measure futures position risk before you enter. Give entry, stop, target, and the size you have in mind — see what you may gain, what you may lose, and whether it fits your own capital rule.

How much futures risk is acceptable?

You set the account rule. The calculator keeps the dangerous edges visible.

Account value now, including open P&L — not the initial deposit.

Open risk means loss to stops, not position value.

Total open-account risk cap

Your rule: maximum 1% open risk$100.00 remains from $100.00 capacity.

What is the futures trade map?

Take-profit matters as much as stop-loss. Without it you only see half the decision.

No live price is fetched. Enter the prices from your own futures plan.

Choose entry money or leverage

Pick one. The calculator solves the other so the futures order stays inside remaining risk capacity.

Formula and leverage note

Leverage = risk capacity ÷ (entry money × stop distance)$100.00 ÷ ($200.00 × 10%) = 5×

Leverage is in a lower range; stop execution is still not guaranteed.

This futures position size calculator is not a buy or sell signal. Stop execution, slippage, gaps, fees, exchange rules, and contract size can change the live result.

Futures position size guide

What this futures position size calculator determines before a trade

Fibonomy derives futures trade-loss capacity from account equity, the total account-risk cap, and risk already open. It then uses the entry-to-stop distance to calculate matching entry money or leverage, position value, asset units, and the order’s effect on account risk. It supports crypto futures plus custom instruments such as forex, gold, stocks, and indices.

  • Stop distance| Entry − Stop | ÷ Entry
  • Matching leverageRisk capacity ÷ (Money × Stop %)
  • Matching entry moneyRisk capacity ÷ (Leverage × Stop %)

The calculator is the plan. The journal is the trade.

Once the futures size is on an exchange, Fibonomy shows mark price, exposure, and the note you wrote — not another spreadsheet.

FAQ

What does this futures position size calculator calculate?

It uses account equity, the futures risk cap, open-position risk, entry, and stop-loss to calculate trade-loss capacity. It then derives matching entry money or leverage, position value, and asset units.

What is the futures leverage formula?

Matching leverage equals remaining risk capacity divided by entry money multiplied by the percentage distance from entry to stop-loss.

Does a matching result mean the futures trade is safe or profitable?

No. A matching size only means the order fits the entered risk rule. It does not validate direction, guarantee stop execution, or predict profitability.

Why does the futures calculator ask for take-profit?

Take-profit estimates profit, reward-to-risk, and break-even win rate. Futures position size is still derived from risk capacity and stop distance.

Can I trade this futures size as-is?

No. This is a planning tool. Fees, mark price, contract size, and exchange increments still change what you can actually hold.
