Sizing for how you trade
Position sizing for swing trading
Hold a perpetual for three days and you pay funding somewhere between six and thirty-six times, depending on the pair. It is the cost swing traders most often leave out of the plan, because unlike commission it arrives quietly while you are not looking.
What goes wrong
- Funding differs per coin and per venue, and the interval is not always eight hours
- A position held over a weekend can pay more in funding than it did in commission
- A wide stop hides the cost: the percentages look small next to the move you are after
What ZRisk does about it
Funding for your holding time
Set how many funding periods you expect, from the live rate or by hand, and it is priced into the risk.
Per pair, per venue
Rates and intervals are read for the exact pair, and the same trade is compared across the exchanges you use.
Break-even drawn on the chart
Including the commission already paid and the exit still to come, so you can see the price the trade is genuinely flat.
The least you need on the exchange
Not just the margin, but the amount that survives the trip to your stop. The rest of your capital can stay off the venue.
In numbers
A position held four days on a pair funding at 0.01% every eight hours pays 0.12% of its value, which on a 3% stop is four percent of the risk you set, spent without a single price tick going against you.
