Switching From Crypto CFDs to Perpetuals: A Position Sizing Example

A worked BTC example for traders moving a strategy from crypto CFDs to USDT perpetuals.

2 min read3 sections

Moving a strategy from a crypto CFD to a linear USDT perpetual changes the units on the order ticket. It can also change the price that triggers an order, the cost of holding the position and the evaluation rules that apply.

This example starts with a BTC position and works through the numbers you would check before reproducing a trade. The prices and fee rates are illustrative.

01/ 03

Translate the size from lots to BTC

Check the contract size in the old CFD ticket. If the platform defines one lot as one BTC, 0.10 lots gives 0.10 BTC of exposure. A different lot size would give a different exposure from the same order ticket.

For a linear BTCUSDT perpetual quoted in BTC quantity, 0.10 BTC at 60,000 USDT per BTC is 6,000 USDT of notional. Check the symbol’s quantity step and minimum before entering the order.

Estimate the loss at the stop

A long entry at 60,000 and an exit at 59,500 would lose 500 USDT per BTC. For 0.10 BTC that is a 50 USDT price loss. Changing leverage with the same size changes the initial margin, while the price loss in this example stays 50 USDT.

At an illustrative fee of 0.06% per side, the entry costs 3.60 USDT and the exit costs 3.57 USDT. One funding payment of 0.01% at a 6,000 USDT position value would add 0.60 USDT if the position pays funding. Together the hypothetical loss is 57.77 USDT before slippage.

Check the stop and the remaining evaluation limits

Check whether the new order uses the last trade price, mark price or another trigger. A trigger activates the order. The fill may occur at a different price, especially in a fast or thin market.

Compare the estimated loss, costs and any open exposure with the daily and maximum loss room currently shown on your account. Check the plan’s equity calculation and reset schedule before carrying a position over a session boundary.

Frequently asked questions

01Can I copy my CFD lot size directly to a perpetual order?

Check both contract specifications first. Convert the CFD lots to the underlying exposure, then translate that exposure into the quantity units and increments accepted by the perpetual venue.

02Does more leverage change the loss at my stop?

For the same quantity and exit price, the price loss is the same. Leverage changes the margin needed and can affect how close the position is to liquidation.
