Two of the core factors work together to answer one question: was this a genuine sample of trading decisions, or one or two lucky bets? Trade count looks at how many trades you took. Trade concentration looks at whether your profit was spread across them or leaned on a single winner. Together they separate a trader working a plan from someone who got a windfall and stopped.
Trade count: a real sample
The trade-count factor rewards taking a genuine number of trades rather than placing a single bet and walking away. The credit rises quickly over your first several trades and then keeps climbing more gently. A steady book of trades reads as deliberate. Importantly, trading a very high number does not get punished; it brings only a slight easing, because extreme trade counts can signal over-trading. There is no magic number to hit. A handful of real, planned trades is plenty.
Concentration: spread across trades
The concentration factor looks at whether your profit came from across your trades or from one outsized winner. It does not just check your single biggest trade; it looks at the whole distribution and asks how many trades your profit was effectively spread across. Profit spread evenly over several trades earns full credit. Profit that leaned almost entirely on one trade is reduced toward a floor, concentrated but never zeroed, because one huge winner is hard to repeat and the score is paying for repeatability.
A note on what changed
Concentration is about the spread across your trades, not across markets. The Desk used to score symbol diversification, which asked how many instruments you traded, but that factor has been retired. The score no longer cares how many markets you touch. Trade one instrument or six, specialist or generalist, and you are judged only on how you trade, not on how widely. This is good news for specialists, who are now scored purely on execution quality.
