Why traders blow accounts even with a "good" strategy
Same size, every day, regardless of conditions
Most traders risk the same 1% (or whatever they picked once) no matter how calm or violent the market is right now. The fix: size down automatically when today's ATR is running hot, size up when it's calm — same edge, less exposure to the moves that actually blow accounts.
No real signal for when to cut size
"Trade smaller when it's risky" is common advice with no actual number behind it. The fix: a real multiplier — 0.55x, 1.2x, whatever today's ATR calls for — using the indicator you already have on your chart, not a vague feeling.
Sitting out entirely during volatile weeks
The opposite mistake — going flat and missing the bigger moves a high-ATR day actually creates. The fix: stay in with a smaller, appropriately-sized position instead of an all-or-nothing choice.
"I don't even know my volatility number"
Most sizing tools ask for numbers you've never heard of. The fix: this one only needs ATR — a standard indicator already built into TradingView, MT4/5, NinjaTrader, and cTrader. If you can read your chart, you can use this.
Not Just Another Position Size Calculator
Most position size calculators ask one question: "what's my size today?" — using today's raw ATR alone, with no memory of what's normal.
This one asks a different question: "is today different from normal — and by how much?" It compares today's ATR to your own baseline for that instrument, not a generic one-size formula. That's the difference between reacting to a number and actually catching when conditions have changed.
It's also bounded (0.25x–2.0x) so a freak low-liquidity reading can't recommend an absurdly oversized position, and it tells you the regime in plain English — not just a number to interpret yourself.
See It In Action
Works for any instrument (e.g. ES/NQ, Gold, forex pairs) — anything with a chart. Since it compares a ratio, not an absolute number, you don't need to tell it which instrument you're using — just read both ATR values off that instrument's own chart.
