Harmonic Strategy Suite Pro
Most harmonic indicators draw a pattern and leave you guessing whether it is
worth trading. This one answers that question: every pattern it finds is
replayed against the chart's own history, so you see the real hit rate of each
pattern type on the instrument and timeframe in front of you - before you risk
anything.
What it analyses
The indicator works purely from price structure - no indicators layered on
indicators, no repainting of confirmed patterns.
An original pivot engine sweeps the chart across a whole range of swing depths
at once, so it catches structures at several scales instead of only the one
your settings happen to favour. Consecutive same-direction pivots are merged to
the true extreme, giving a clean alternating high-low-high sequence.
Every consecutive five-pivot window (X-A-B-C-D) is then measured against the
published Fibonacci definitions of six classic harmonic patterns:
Gartley B at 0.618 of XA, D at 0.786
Bat B at 0.382-0.50, D at 0.886
Butterfly B at 0.786, D at 1.272-1.618
Crab B at 0.382-0.618, D at 1.618
Shark B at 1.13-1.618, D at 0.886-1.13
Cypher B at 0.382-0.618, C at 1.272-1.414, D at 0.786
A tolerance setting controls how strictly those ratios must be met, and each
detection is scored 0-100 by how close it sits to the ideal ratio - so a
textbook Gartley is visibly distinguished from a loose one.
The backtester - what makes this different
This is the part most harmonic tools do not have.
For every pattern found, the indicator simulates the trade that pattern would
have produced:
- A limit order is placed at the D completion point.
- If price reaches the target or the stop BEFORE touching D, the setup is
treated as invalidated and never becomes a trade - exactly as a real
resting order would be cancelled.
- Unfilled orders time out after 15 bars.
- Filled trades are then followed bar by bar to see whether they reached
Target 1, Target 2, or the stop first.
Those results are compiled into an on-chart dashboard showing, per pattern type:
Patterns found | Entries filled | Target 1 hit rate | Target 2 hit rate |
Average return | Total return
with a combined total row. Losing rows are highlighted, and each pattern type
has an ON/OFF button that instantly filters it off the chart. The panel
collapses to a single title bar when you want a clear view.
You can see at a glance that, for example, Cypher fills rarely but converts
often on this pair, while Crab fills more and converts less. That is a
judgement you can act on - and it is measured on your broker's data, not
quoted from a book.
How to read the chart
Each pattern is drawn as its X-A-B-C-D skeleton with shaded triangles. The
shading is not decorative: the more often that pattern type reached Target 1 in
the backtest, the more solid its fill, so reliable structures stand out
immediately.
Every pattern carries its full trade plan:
Gold Entry line, labelled BUY ENTRY / SELL ENTRY with the exact price
Mint Target 1, labelled with the price and that pattern's T1 hit rate
Ice blue Target 2, same treatment
Red Stop loss
Line styling tells you what happened. A level that price actually reached is
drawn SOLID and stops on the bar it was hit. A level that was never reached
stays DOTTED and runs to the end of the setup. A gold dot marks the
confirmation bar. Labels sit at the end of their own line, with a leader drawn
in whenever one has to be nudged to stay readable.
Pattern name and accuracy are printed beside each structure, positioned below
bullish setups and above bearish ones so they never sit on the price action.

Who it is for
Suited to traders who already understand harmonic patterns and want the
donkey work automated plus evidence attached - and to intermediate traders who
know the shapes but are not sure which ones to trust.
It is genuinely useful for swing and intraday traders on any instrument and any
timeframe: forex, indices, commodities and crypto all work, because the logic
is pure price geometry.
If you have never met a harmonic pattern before, read up on the basics first.
The indicator will find them for you, but it assumes you know what a Gartley is
trying to tell you.
Typical use
1. Attach to a chart and let the dashboard build its sample.
2. Look at which pattern types actually perform on that instrument and
timeframe, and switch the weak ones off.
3. Wait for a fresh completion at D, checking the accuracy score and that
type's historical hit rate.
4. Use the drawn entry, stop and targets as the plan, sized to your own risk.
Important notes - please read
- This is an ANALYSIS TOOL. It does not place, modify or close any order.
There is no auto-trading and it never touches your account.
- Past performance is not a prediction. The dashboard reports what these
patterns did historically on the loaded data. It is evidence for a
decision, not a guarantee of the next one.
- Statistics need a sample. cTrader only gives an indicator the bars the
chart has actually loaded, so scroll back to load history before judging
the numbers - the difference between a few hundred bars and several
thousand is the difference between noise and a usable sample.
- Returns are shown as a percentage of price. A forex pair will naturally
show smaller percentages than an index or a commodity; compare like with
like.
- Entry fill rates are realistically low by design. Many harmonic setups
never fill because price runs away from D first. The indicator counts
those honestly as unfilled rather than flattering the statistics.
- Deep scans do real work. If you push the bar count high on a slow machine
and see a pause on each new bar, reduce Historical Bars to Scan or raise
the minimum pivot depth.
Analysis only. No DLLs. No external connections. It never sends, modifies or
closes an order.
