Tool
Smart Stop Calculator
Set stops where the market actually moves, not where you guessed.
Why your stop keeps getting hit
Most beginners pick a stop loss by feel: I'll use 2%. That works if 2% is wider than today's noise. It doesn't if the coin's average daily range is 4%, because a random wick hits the stop before the trade plays out.
This tool reads the last 14 days of price action and tells you, in dollars, where a sensible stop actually lives for this coin right now. Then it hands the number to the Perp Coach so you can build the rest of the trade around it.
Step 1 · Pick the asset
We'll pull the last 30 days of candles from the exchange you pick.
Exchange
Either works for major coins. Binance has the higher data quality on big symbols; Hyperliquid is fully on-chain.
Asset
Only listed perps. Tokenized stocks (XAUT, NVDA) need spot data, not perp candles.
Direction
Long = price up. Short = price down. Direction flips the side your stop sits on.
Step 2 · How tight or wide?
All three options are anchored to current volatility. Tighter = more leverage allowed, more chance of getting stopped. Wider = the opposite.
Step 3 · Where are you opening?
We use the current mark price by default. Override only if you want to test a hypothetical entry.
Hypothetical entry (optional)
Leave at 0 to use live mark price. Use this to plan a future entry.
What is ATR?
ATR (Average True Range) is the average size of a day's candle over the last 14 days. It's the standard way to measure how much a market "normally" moves.
We multiply ATR by your aggression choice to get the stop distance. Anchoring to ATR instead of a round number means your stop scales with the market: when BTC gets calmer, stops tighten; when it gets choppy, stops widen automatically.
