The bars
The Fisher transform
The Fisher transform is +5.08, above its trigger at +4.82.
- The reading
- It is stretched high (above +1.5): the price sits near the top of its recent range and has stayed there. It has been above its trigger for 10 bars.
- How it is read
- The transform stretches prices near the edge of their range into sharp peaks, so turns stand out. Many traders read a cross of the trigger as a turn, and give it more weight when it comes from a stretched reading beyond ±1.5.
- Read it with care
- It turns fast and crosses often, especially in sideways markets, and a stretched reading can stay stretched in a strong trend. It gives no timing for the next bar.

Education only, not investment advice. The answer comes from the numbers you typed in, not from your account or the market. Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it.

Turns made easy to see
John Ehlers published the Fisher transform in 2002. Prices are not spread like a bell curve, so he took each bar's midpoint, placed it in the range of the last 9 midpoints on a scale from -1 to +1, and passed it through the Fisher formula, which stretches values near the edges. Most readings stay small; the ones near a turn grow into sharp peaks.
Compare it with the stochastic oscillator, which reads the same range without the stretch, check momentum with the RSI calculator, and size the trade with the position size calculator.
