Formula
The formula is displayed so the result can be checked independently. PreBreakout does not use a hidden scoring model on this page.
Worked hypothetical example
If a hypothetical range spans 80 to 100 and the breakout level is 100, the pattern height is 20 and the upward measured-move result is 120.
Important: the numbers are fictional and are not associated with a security, issuer or current market price.
What this calculator does not tell you
- The projected level is only the mechanical output of the measured-move formula.
- Pattern geometry does not predict whether price will reach the calculated level.
- Use fictional inputs for learning if you do not want to model a real instrument.
Market execution can differ from arithmetic inputs because of spreads, gaps, slippage, order types, broker constraints and other factors. This tool does not attempt to model those effects unless an input explicitly asks for a value.
How to use it for learning
Change one input at a time and observe how the result changes. This is especially useful for understanding sensitivity: wider stop distance changes position-size arithmetic, a taller pattern changes a measured-move result, and a larger reward-to-risk ratio changes the theoretical break-even win rate. The exercise is about the formula, not about identifying a trade.
