Dislikedhowever there is one logical error because of this the daily balance is showing wrong. the lotsize doesnt change daily. its fixed at start of the month, only TP changes daily.Ignored
When *I* am trading (and of course, that doesn't have to be the same way you trade it), I actually do calculate the lot size every day based on what 2.5% of the balance is that day. In the end, it makes very little difference - what it amounts to is a few pips difference when we get close to the target... If we're already up several %, our lot size would be slightly higher, and therefore the pips needed to reach the final few % would be slightly fewer. But again, the difference is minimal, and it does make the math a whole lot easier to stick with the same lot size for the entire month. Only reason I do it this way is because my EA calculates this stuff "on the fly" at the time it places the trade. So I just very quickly calculate what 2.5% of the current account balance is at the time of the trade, instead of needing a variable for it.
