Risk and position sizing

Open-position scenario risk ledger

Record contract units, a shared price shock, estimated costs and combined scenario P&L across open crypto positions.

Start with one declared scenario

The sample rows apply a fictional 5% decline to two long positions. They demonstrate unit arithmetic only; the shared-driver label is a sensitivity assumption, not a measured correlation.

Position	Entry → stress	Price P&L	Costs	Net scenario P&L
0.02 BTC spot	$60,000 → $57,000	−$60	$1	−$61
0.5 ETH linear perpetual	$3,000 → $2,850	−$75	$2	−$77
Combined	Both markets −5%	−$135	$3	−$138

Price P&L = side sign × quantity × multiplier × (stress price − entry price)

Net scenario P&L = price P&L − estimated fees − estimated funding or carry

Confirm contract units and quote currency first. The CSV example uses a multiplier of 1 for both fictional linear calculations. Real contract multipliers, fees, carry, fills and margin rules vary.

HOW TO USE THIS LEDGER

Copy a scenario ID across positions that share a declared shock, then record each instrument's own quantity, multiplier, quote currency, mark and cost assumptions. Compare position rows and combined P&L; do not infer a probability or correlation from the label.

What does this download contain?

Two fictional long-position rows, one 5% downside scenario and a blank row for extension. Inputs are invented and for arithmetic demonstration only. It does not calculate correlations, liquidation, a worst case or live venue costs.

This resource is educational, not individualized financial advice. Calculator inputs stay in your browser. Check your venue's current contract, margin and fee documentation.
