Rekt Report: position size decides if you survive — not your entry

I've watched accounts with a genuinely good strategy still go to zero. Not because the entries were wrong — because the size was. A winning edge and a blown account are not opposites; you can have both at the same time, and the bridge between them is one number you set yourself: risk per trade. So let's run the arithmetic that decides which side you land on.

Losing streaks are normal, not bad luck

Say you win 55% of your trades — a solid edge most traders never actually reach. A 55% win rate still means you lose 45% of the time, and losses cluster. The chance of a given losing streak is just the loss rate to the power of the streak length:

• 4 losses in a row: 0.45⁴ = ~4.1% — happens roughly 1 in 24 trades
• 6 in a row: 0.45⁶ = ~0.83% — about 1 in 120
• 8 in a row: 0.45⁸ = ~0.17% — about 1 in 600

Trade a few hundred times a year — easy for any active trader — and a 6- or even 8-trade losing streak isn't a freak event. It's a near-certainty you will hit one. The only question that matters is: does your account survive it?

The same streak at three position sizes

Take a $1,000 account and an 8-trade losing streak. Watch what risk-per-trade does to it:

(Each loss is taken on the remaining balance, the way real risk-management works — 1% risk means 0.99⁸ of the account survives.) At 1% the streak is a scratch you barely feel. At 20% the same eight losses — from a winning strategy — leave you down 83%, needing a +495% gain just to get back to even. That's the asymmetry of drawdown: losses and the gains to undo them are not symmetric, and the gap explodes as size grows.

This is risk of ruin, and it has a threshold

"Risk of ruin" is the probability that a string of losses takes you below the point of no return before your edge can play out. The brutal part is that it's non-linear in position size. Past a certain risk-per-trade, even a positive edge has a real, standing chance of zeroing the account — the math stops protecting you and starts working against you. Below that threshold, a positive edge is close to immortal; above it, you're one ordinary streak from the exit. The line for most realistic edges sits low, which is exactly why the old desks landed on 1–2% per trade long before anyone called it the "1% rule."

Why entry obsession misses the point

A better entry might nudge your win rate from 53% to 56%. Worth having. But it does almost nothing to save an account sized at 15% risk — that account dies on variance regardless of how clean the entries are. Cutting risk-per-trade from 10% to 2%, by contrast, can move you from "likely ruin" to "basically can't be ruined" with the same strategy. One of those levers is worth a few percent; the other decides whether you're in the game at all. Most traders spend 90% of their attention on the small lever.

What the math says to do

• Pick risk per trade first, entry second. Decide the dollar you're willing to lose before you look at the chart. 1–2% of the account is the boring, correct answer.
• Size the position from the stop, not the vibe. Position size = (account × risk%) ÷ (distance to stop). That's a calculation, not a feeling — and leverage falls out of it, it isn't an input you crank.
• Respect the recovery curve. Anything past ~30% drawdown needs a 50%+ gain to undo. Past 50% you need to double. Don't let size put you there.
• Assume the streak is coming. Over a year you will hit 6+ losses in a row. Size so that day is a Tuesday, not a funeral.

None of this requires a better strategy, a faster feed, or a secret indicator. It's one division you do before the trade instead of one autopsy you do after. The entry is what people talk about. The size is what keeps them here to talk about it. Run yours below.

Method: streak probabilities are loss-rate^streak for an assumed 55% win rate (independent trades). Balance after N losses uses (1 − risk%)^N on the running account; recovery % is the gain needed to return to the starting balance. These are exact arithmetic illustrations, not a backtest; real results vary with win rate, reward-to-risk, fees and funding, all of which only widen the gap between small and large position sizes.
