How to use this calculator
Each step names a control you will find on screen above.
- Look at the bare chart first
Before touching the toggle, try to mark where you think price kept reversing. Commit to your own reading.
- Show support & resistance levels
Turn the toggle on. The price data has not changed by a single rupee — only whether the levels are drawn.
- Count the touches
A level is only interesting if price has turned at it more than twice. Two touches is a coincidence; four is a level other people are watching too.
- Watch a broken level flip roles
Find a place where price broke above resistance and later came back to it as support. That role reversal is the most useful thing on the chart.
Worked example: A level that held four times
Toggle the levels on and find the horizontal line with the most touches. Note what happened at each one.

A calculator gives you a number. These explain what the number means and when it misleads you.

- Technical Analysis11 minThe 52-week high: the level people get backwardsMost investors treat a new high as a reason to wait. Decades of evidence across markets say it is closer to the opposite, and the reason why is a behavioural quirk.
- Risk & Psychology11 minWhen life, not the market, is the problemIllness, separation, bereavement, a business failing. The portfolio is rarely the thing that needs attention, and it is often the thing that gets damaged.
