Round-turn cost per trade, and what share of your risk it eats.
Round-turn cost per trade, and what share of your risk it eats. The page states the equation, the units it expects and the rounding it applies, so the result can be reproduced by hand.
A calculator gives you a number. This one feeds the next: account to risk, risk to position size, position size to the trade, and the trade to expectancy, drawdown and risk of ruin.
See the performance tools →Commission is charged per side, so a round turn is twice the quoted rate. The spread is paid once, on entry.
One lot, $3.50 per lot per side, 0.2-pip raw spread:
A zero-commission account quoting a 1.0-pip spread costs $10.00 on the same trade. Compare the total, not either half.
Often by a little, sometimes not at all. A 0.2-pip spread plus $7 commission is $9 per lot; a 1.0-pip zero-commission spread is $10. The gap narrows further on wider spreads.
At $9 per trade and 200 trades, $1,800 — 7.2% of a $25,000 account, paid regardless of whether the strategy works.
On both, for most brokers, so a quoted rate of $3.50 per lot is $7 per round turn. A few quote the round turn directly — check which before comparing accounts.
A calculator answers one question and raises the next. These are the ones this figure feeds into.
The spread in currency terms, and as a percentage of the risk on the trade.
The move required to cover spread, commission and financing before anything is profit.
Potential profit and loss on a trade, with costs included rather than assumed away.
