A stop-loss is the price at which a losing trade closes automatically — the mechanism that turns 'this could go very wrong' into 'this can only go wrong by a known amount.'
A stop-loss is a pre-set exit price attached to a trade the moment it opens. If the market moves against the position and reaches that price, the trade closes automatically — no judgment call in the moment, no hoping it comes back. The whole point is that the maximum possible loss on any single trade is known and bounded before the trade ever happens.
The RSI on entry was 47.3 — a normal, not-extreme reading. Stop-losses aren't a sign something went wrong; they're the plan working as designed when a trade simply doesn't pan out.
On this account, the stop distance comes from ATR (a volatility measure), and the position size is calculated backward from that distance so the dollar loss, if the stop is hit, lands at a fixed percentage of account equity — currently 0.5%. That's why losses across very different symbols (gold, Bitcoin, EUR/USD) tend to land in a similar dollar range even though their price scales are completely different.
