Consistency Notes When Overnight Financing Changes a Day's Net Profit

I keep two versions of each trading day in my journal: the raw closed profit and the number after costs. Overnight financing is the reason. If I hold a position past the session, the broker may charge or credit financing, and that amount can turn a small winner into a small loser. Commissions do the same thing, but financing can be easy to miss because it posts separately.

For consistency rules, the question is not whether I think financing should count. The question is what the rule says. I read the wording for “net profit,” “realized profit,” and “trading day” before I assume anything. Some programs may calculate day totals from closed trades only. Others may include commissions, swaps, and other account charges. I check the provider’s own current terms instead of relying on a summary.

My routine is simple. I record gross closed profit, commissions, and overnight financing as separate columns. Then I calculate net profit for the day. If I held a position overnight, I note the financing entry and the time it posted. I also note whether the charge belongs to the day the position was opened or the day it was closed, because that can affect a day total.

A hypothetical example helps me test the wording. Say I close a trade for $80 gross. Commissions are $6. Overnight financing is $14. My net is $60. If I had another trade that lost $55 after costs, the day is still green, but less green than the gross number suggests. If the rule uses gross closed profit, I want to know that before I count the day as a consistency win.

I keep a short checklist:

• Gross closed profit by day.
• Commissions by day.
• Overnight financing by day.
• Rule definition of net profit.
• Any cost posting date.

When financing changes a day total, I do not adjust my journal to match what I hope the rule means. I write down the exact wording and keep the calculation transparent. That makes it easier to review at the end of the month. If a day is close to a rule boundary, I treat the financing cost as material and recheck the provider’s current terms. The prop firm consistency financing-cost note is the kind of reference I keep nearby when I compare my day totals with the rule language.
