Profit Lock: volatility-aware stop-loss levels that protect your gains
Profit Lock helps investors turn an open position into a clear exit plan. It compares several stop models, grades the quality of each level, and shows the risk before you make a manual decision.
How it works
- Describe the position. Enter the ticker, your entry price, share count, and how much risk you are comfortable with. PnLock pulls recent daily candles to work from.
- Compare six models. Fixed-percentage, ATR-based, swing-low, moving-average trend and trailing Chandelier-style exits are computed side by side and anchored to the current price, not your entry.
- Read the quality grade. A 0–100 score grades each level on noise tolerance, distance from price, model agreement, and how fresh the data is, then maps it to an A–F grade.
- Act manually. Place the level you choose with your broker, or send it to a connected Trading 212 account in one click, and re-run as volatility or trend changes.
What it helps with
Instead of choosing a random percentage stop, Profit Lock accounts for current price, volatility, recent structure, and model agreement. The goal is a stop level with enough breathing room for normal noise while still limiting a real reversal.
Built for disciplined exits
Six built-in models cover fixed buffers, ATR-based volatility, swing lows, moving-average trend breaks, and trailing Chandelier-style exits. Custom models from the backtester can also be reviewed inside the app.
Decision support, not advice
PnLock does not promise returns or tell you what to buy or sell. It presents risk metrics and model outputs so you can make your own decision and place any order manually with your broker.
Common questions
What is a profit lock?
A profit lock is a planned exit level for a position that is already profitable. It defines how much of the gain you are willing to give back before exiting.
Is this a trading signal?
No. Profit Lock is an informational risk-management tool. It helps compare exit levels but does not provide financial advice or guarantee outcomes.
Why use volatility instead of a fixed percentage?
Volatility helps account for how much a stock normally moves. A fixed 5% stop can be too tight for one stock and too loose for another.
