KISS Auto Fib Indicator: One Swing, Seven Fixed Lines

Written by Dominic Walsh · Published 12 Jun 2026 · Last updated 18 Sep 2026

The kiss auto fib indicator does one job and stops. It finds the highest high and the lowest low inside `InpLookback` `20` bars. Those two anchor a retracement ladder drawn as horizontal lines.

This build ships as a compiled .ex4 for MT4 and .ex5 for MT5; the screenshots below come from EURUSD H1.

The chart output explained

Horizontal lines mark 0.236, 0.382, 0.5, 0.618 and 0.786.

`InpDrawZeroLine` and `InpDrawFullLine` add the two ends in silver.

`SwingHigh` uses arrow 234 in tomato and `SwingLow` uses 233 in lime green.

Text objects label each line, all named with the `InpObjPrefix` `”KAF_”` prefix.

• SwingHigh: arrow, tomato, width 2, arrow code 234
• SwingLow: arrow, lime green, width 2, arrow code 233

The computation

Two anchors

iHighest and iLowest run over `InpLookback` `20` bars from the previous candle. Their prices become the two ends of the range.

Direction from timing

Whichever anchor formed later decides which end counts as zero. A high that came after the low gives a down leg. The ladder then reads from the top rather than the bottom.

Fixed ratios

Each line takes the zero end and adds a set share of the range. `InpDrawExtensions` `false` keeps 1.272 and 1.618 off the chart until you switch them on.

Reading the output

The gold `InpFib500Color` line marks the midpoint of the swing.

The orange line at 0.618 is the one most traders watch.

Lines redraw whenever a new extreme enters the twenty-bar window.

Arrows simply flag where the two anchors sit.

Alert channels in this build: popup, one message per closed bar.

This build carries a single route. `InpAlertOnNewSwing` ships true and raises a terminal message when a fresh anchor appears. No phone, mail or sound option exists, and a closed bar gates each message.

Placing it well

Twenty bars is a short window, so the ladder moves often. EURUSD H1 is the reference chart, where that covers most of a trading day. On M5 the lines shift several times an hour. H4 holds one ladder for days.

Where the KISS Auto Fib Indicator struggles

A twenty-bar window redraws the ladder as soon as a new extreme prints.

Anchors come from raw extremes, not confirmed swing structure.

Levels are drawn references, so nothing here tests whether price respected one.

Copy the compiled KISS Auto Fib Indicator file into your MQL4/Indicators folder, and the MT5 build into MQL5/Indicators, then restart the terminal and drag it onto a chart. The step-by-step guide with screenshots is at how to install MT4 and MT5 indicators.

FAQ

What does InpLookback 20 anchor?

The highest high and the lowest low across twenty bars, taken from the previous candle back. Those two prices define the range every line sits inside. A longer window gives a steadier ladder that updates less often.

How does InpLookback decide the direction?

By which anchor formed more recently. A high that printed after the low marks a down leg, so zero sits at the top. That single comparison is the whole of the direction logic here.

Why does InpDrawExtensions ship false?

To keep the chart simple, which is what the name of the tool is pointing at. The 1.272 and 1.618 lines sit outside the range and suit target work rather than retracement reading. Switch them on when you want them.

What is InpObjPrefix for?

It names every object this tool creates, defaulting to `”KAF_”`. That prefix lets the code delete only its own drawings when you remove it, leaving your manual lines and boxes untouched.

Are results guaranteed?

No. Trading involves risk. Results are not guaranteed; past performance is not indicative of future results. Use the KISS Auto Fib Indicator as one input. Always backtest before trading live.
