Draw Fibonacci retracements correctly, and see for yourself why two competent people looking at the same chart get two different sets of levels.

How to use this calculator
Each step names a control you will find on screen above.
- Anchor: swing low
Set the starting point of the move you are measuring. It must be a real swing low, not a convenient one.
- Anchor: swing high
Set the end of the move. The levels are simple percentages of the distance between the two anchors.
- Read the levels
38.2%, 50% and 61.8% are the ones people watch. The 50% is not a Fibonacci number at all — it was added because it is a half, and it stayed because it works as well as the others.
- Now move an anchor by a few sessions
This is the exercise. Shift the swing low slightly and watch every level move. Nothing about the stock changed.
Worked example: A move from ₹800 to ₹1,000
Anchor the swing low at ₹800 and the swing high at ₹1,000. The range is ₹200 and every level is a percentage of it.

Where this is taught
A calculator gives you a number. These explain what the number means and when it misleads you.
- Technical Analysis10 minADX and Fibonacci retracementsOne indicator that tells you whether to trust your other indicators, and one that works largely because everyone watches it.
- Technical Analysis13 minMarket regimes: knowing when your system will not workEvery strategy has conditions it needs. Trend systems die in chop, mean-reversion dies in trends — and most losing streaks are a regime change, not a broken system.
- Technical Analysis11 minPrice action: trading a naked chartStrip every indicator off and what remains is structure, levels, momentum and participation — which is where the information was all along.
