Rewind

A test of the tool, not a prediction. Pick a stock and a moment in the past.

1. Freeze

The tool throws away every price bar after the moment you choose. It can only see what you could have seen then.

2. Plan

It prints the exact plan it would have shown you at that moment: entry, stop, targets, odds.

3. Reveal

Then it looks at what the stock actually did next and grades the plan: hit the target, hit the stop, or never triggered.

Why it matters

Run it on a stock that ran and on one that collapsed. If the odds it printed match what happened over 20 or so tries, you can trust them. If not, you learned that for free.

Account and risk

Account sizeYour trading balance. Every position size is computed from it.

Risk per tradePercent of the account you accept losing if the stop loss hits. 2% is the common default; 1% is conservative.

Max positionThe largest slice of your account the tool will put in a single stock. At 25%, even a stock that goes to zero costs a quarter of the account, not all of it.
