How performance numbers are calculated: decisions versus fills

Updated September 6, 2026

If you mirror one setup across several prop accounts, your trade COUNT in Propfy will be lower than your broker's, and your P&L will match. Both are deliberate.

The problem

Mirroring one idea across six accounts produces six fills at the broker. Counted raw, one trade reads as six: six entries, six exits, an overtrading flag you did not earn, and a losing streak six times longer than the one you actually had.

Counts are decisions

Propfy groups mirrors back into the one decision that produced them. Fills join the same decision when all of these hold:

  • Same instrument and same direction
  • Entries within 60 seconds of each other
  • No two fills from the same account

That last one matters: a second fill on an account you already have in the group is a genuine re-entry, so it starts a new decision rather than joining the old one. Mirrors in real trading land seconds apart, not on identical timestamps, which is why the window is a window and not an exact match.

Everything that counts behaviour uses decisions: trades per day, streaks, rule adherence, the dashboard and the analytics.

Money is never deduplicated

Every dollar is real and every dollar is counted. P&L, drawdown, the calendar and payout progress sum the actual profit and loss of every fill across every account. Grouping changes how many trades you took. It never changes how much you made or lost.

Money aggregates use net figures, after broker fees, which is what reconciles with your account balance. The per-fill gross number is preserved in the ledger.

The ledger stays fills

The trades ledger under Journal shows individual fills, one row per account, exactly as your broker reports them. That is the page to reconcile against a broker statement.

So which number is right

Both. A decision count answers "how many times did I trade today". A fill count answers "how many orders were filled". Use the ledger for reconciliation and the dashboard for behaviour.

Risk Disclosure

Futures and forex trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing one's financial security or lifestyle. Only risk capital should be used for trading and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.

Hypothetical Performance Disclosure

Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. For example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all of which can adversely affect trading results.
