Five charges, and the one everybody quotes is the smallest
[Ad] This blog uses affiliate advertising.
I used to compare brokers on a single advertised number and then wonder quietly where the balance had gone. Writing the charges out in the order they actually land fixed that.
There are five, and only one of them is the number in the advertisement. Conversion on the way in, charged before I have placed a single trade. The quoted difference between buy and sell, paid on entry. A per-lot charge, where the account carries one. An overnight financing amount for every night a position stays open. Then conversion again on the way out.
The first and the last are the ones I never counted, and they never appear on a fee schedule because they are not presented as fees at all. They are margins built into an exchange rate, which makes them easy to miss and easy to underestimate.
The whole thing fits on one line for a single position: the quoted difference, plus the round-turn per-lot charge, plus the overnight amount multiplied by the number of nights held, plus both conversions. Adding the last two terms changed which account type looked cheapest for the way I actually trade.
Which is the real point. The cheapest account on paper and the cheapest account for a shilling-funded trader holding positions for several days are not reliably the same account.
