You can be too small to get paid
Every risk conversation in prop trading is about ceilings: the trailing drawdown, the daily loss limit, the blowup. This post is about the opposite thing, because the simulation kept insisting on it: Tradeify's rules also put a floor under risk. Trade too small and the account doesn't blow up — it does something stranger. It survives forever and never pays you a dollar.
The rule that does it
A Growth 50K payout requires, among other things, five trading days each showing more than $150 of
profit since the last payout. Our playbook targets 2.4R with outcomes jittered ±50%, so a single winning
trade pays between 1.2 × risk and 3.6 × risk. Set risk to $40 and your best possible
winner is $144 — no single win can ever qualify a day. The share of winners that clear the bar is pure
arithmetic:
Share of winning trades that clear the $150 qualifying bar, by risk per trade
What it does to the account's value
Here's the same fact through the lifecycle simulator — expected remaining payouts from a funded account sitting at the +$2,100 floor lock, swept across risk per trade:
Account EV vs risk per trade — funded, +$2,100, floor locked
The left edge is the finding. At $25 risk the account is nearly unkillable — and nearly worthless, because the payout engine never turns over: it can't assemble five qualifying days, so the money stays locked inside a simulated account forever. EV doesn't fall to zero because of ruin; it falls because of a gate that small size can't open.
Why this matters for the policy
- "Protect the cushioned account" does not mean "risk as little as possible." It means risk the smallest amount that still runs the payout engine — with our numbers, comfortably above the ~$65 cliff, and in practice the optimizer lands at $150–$300 once the floor is locked.
- The floor moves with the firm: the 25K account's bar is $100, the 100K's is $200. Same playbook, different minimum viable size on each.
- If you grind $50-risk trades on a locked account because it feels safe, you have converted a several-thousand-dollar asset into a terrarium. It's alive. You just can't eat it.
