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.
