What is 61.8 Signals?

01 The math behind 61.8

61.8% is the inverse of the golden ratio φ ≈ 1.618. The same proportion appears in nautilus shells, the Parthenon, and 90+ years of market chart analysis.

The formula

φ  = (1 + √5) ÷ 2  ≈ 1.6180339887...
1/φ = (√5 − 1) ÷ 2  ≈ 0.6180339887...

The 61.8% Fibonacci retracement level is 1 ÷ φ expressed as a percentage. When a market makes an impulsive move and pulls back, the 61.8% level is a common reversal zone — both because of math and because every trader watches it.

02 The strategy in plain English

Three components: detect an impulse, wait for it to retrace 61.8%, and only fire if the volatility regime makes mean reversion likely.

The 3-entry ladder

When an impulse is detected and price starts retracing, the system offers three entries — each at a deeper retracement level:

Take-profit ladder

The volatility-regime gate

Before any signal fires, we check the instrument's volatility coefficient:

VolC = recent average daily range ÷ older average daily range

• VolC < 1.0 — volatility falling, regime favors mean reversion → signal fires.
• VolC > 1.0 — volatility rising, regime hostile to retracement plays → signal silenced.

03 The multi-instrument dashboard

The dashboard shows all 15 instruments at once, each as a mini-card with a live price, setup status, and a small candle chart. Click any card to drill into the focused chart view.

What each card shows

• Instrument name + icon — quick visual identification.
• Phase — SCANNING (waiting for impulse), SETUP VALID (impulse found, watching for retracement), ENTRY_1/2/3_SIGNAL (signal fired).
• Current price + day change — live ticker.
• Mini candle chart — recent price action with HIGH/LOW markers and fib lines.
• VolC + win rate badge — instrument's vol regime status and backtest win rate.

04 The focused chart

Click any dashboard card to open the focused view. This is where you'll spend most of your time — live candles, all the fib levels, entry pills, and the expected-resolution projection.

What you can do on this view

• Watch live — chart refreshes every 5 seconds with new candle data.
• Toggle Auto-Fib — turn the automatic fib detection on/off (default ON).
• Toggle Hint — show/hide the gold status hint ("Retracing → wait for 61.8%") that overlays the chart.
• Resize the Hint — drag the bottom-LEFT corner of the hint to make it bigger or smaller.
• Adjust Min Impulse + Stop Buffer — per-instrument config to fine-tune detection sensitivity.
• Draw a manual fib — test your own analysis (see Section 6).
• Run sim trades — backtest the current setup on past candles (see Section 8).

04a Min Impulse — the noise filter

"Min Impulse" is the single most important configuration knob on the focused chart. It tells the analyzer how big a price move has to be before it counts as a real impulse — versus random noise that the strategy should ignore.

What it actually measures

An "impulse" in 61.8 is the price range between an absolute high and an absolute low within a recent lookback window of candles. For an UP setup, the impulse is measured from the low to the high preceding it; for a DOWN setup, from the high to the low. Either way, the size is just |high − low|.

The Min Impulse threshold says: if that range is smaller than this number, treat it as noise. Don't compute fib levels. Don't fire any signals.

if (impulseSize < minImpulse) {
  phase = 'IMPULSE_TOO_SMALL';
  return; // no fib levels drawn, no signals broadcast
}

Why the threshold exists

• Filter out micro-moves. A 0.02-point wobble on UUP isn't a real impulse — it's tick noise. There's nothing meaningful to retrace.
• Improve signal-to-noise ratio. Without this filter, the analyzer would fire on every minor swing, generating dozens of low-quality alerts per hour.
• Keep retracement targets meaningful. A 61.8% retracement of a 5-cent move is 3 cents — too small to trade profitably against any reasonable spread.
• Protect the backtest stats. Including tiny noise-impulses would inflate trade counts and distort win-rate calculations.

Per-instrument defaults

Min Impulse scales with the instrument's typical daily range, so the default value varies widely. A 50-point move on Bitcoin is trivial; a 50-point move on UUP would never happen.

These are tuned to roughly half of each instrument's recent 30-day average daily range. That ratio gives the analyzer enough room to detect a meaningful intraday swing without firing on every minor tick.

The "Auto" button — what it actually computes

Next to the Min Impulse and Stop Buffer fields, the Auto button pulls the instrument's average daily range over the last 30 trading days from the worker's market-history endpoint, divides it by 2, and writes the result into the Min Impulse field.

// Pseudo-code for what Auto does:
const dailyRange = avg(candles.map(c => c.h - c.l)); // 30-day mean
const recommended = dailyRange / 2;
inputMinImpulse.value = recommended.toFixed(2);

Why half of the daily range? Because we want to detect intraday swings, not full-day moves. Half-day-range is empirically a reasonable threshold: small enough to catch real impulses, big enough to filter out chop.

The "30-day avg" status line displayed in the cfg-row shows this number live, so you can see how the auto value compares to the instrument's actual recent volatility.

How to tune it manually

What happens BELOW the threshold

When the current price action's impulse falls below Min Impulse, the chart enters IMPULSE_TOO_SMALL phase. You'll see:

• HIGH and LOW markers still drawn — so you can see what range the analyzer is measuring.
• NO fib levels rendered — there's nothing to retrace from.
• NO entry pills — no E1/E2/E3/TP/SL pricing.
• NO Telegram broadcast — the bot stays silent on this instrument.
• Status text: "Waiting for a bigger impulse" or similar.

This is the analyzer being honest: I don't see anything worth trading right now. It's not broken; it's behaving correctly.

Relationship to other parameters

Common mistakes

A worked example

Suppose you're watching UUP and the 30-day average daily range is reported as 0.085. The Auto button writes 0.04 into Min Impulse (rounded down from 0.0425).

• UUP swings from 28.45 to 28.51 over 30 minutes — that's a 0.06 impulse. Above 0.04 → analyzer registers it, draws fib levels, watches for retracement.
• UUP wiggles between 28.49 and 28.51 for 20 minutes — that's a 0.02 impulse. Below 0.04 → analyzer ignores it, phase stays "IMPULSE_TOO_SMALL".
• UUP makes a clean 28.40 to 28.60 move — that's a 0.20 impulse. Well above 0.04 → strong setup; signal fires if it retraces to the 61.8% level (~28.48) AND vol-coefficient is favorable.

Why this is one of the most underrated knobs

Most retail traders fixate on entry signals — "the strategy" — and ignore the meta-question of when the strategy is even worth running. Min Impulse is the gatekeeper for that. A well-tuned Min Impulse is the difference between a system that signals 50 times a day (mostly noise) and one that signals 5 times a week (mostly actionable).

If you only adjust two knobs on the dashboard, make them Min Impulse and your position sizer's Risk %. Everything else is downstream of those two.

05 Auto-detected signals

The Auto-Fib analyzer continuously scans for impulses and watches for 61.8% retracements. When all conditions align, it broadcasts a signal to Telegram.

The phase machine

The "satisfaction" filter

Once an impulse has been retraced 61.8%, the analyzer retires it. This prevents the same setup from re-firing every 10 seconds while price wobbles around the level. The next signal will only fire when a brand-new impulse forms.

06 Manual fib drawing

Want to test your own setup ideas? Draw your own fib anywhere on the chart. Same entry/SL/TP math as the auto analyzer — but using your anchor points.

1. Click DRAW MANUAL FIBCursor changes to crosshair mode.
2. Click two points on the chartThe first click sets the impulse start (100%), the second sets the end (0%). Direction is determined by which is higher.
3. Drag the endpoints to adjustBlue draggable nodes appear at start and end. Move them to refine your anchors.
4. Read the levelsBlue dashed lines show 23.6 / 38.2 / 50 / 61.8 / 76.4 / 100%. Blue E1/E2/E3/SL/TP1/TP2/TP3 pills appear on the LEFT side (auto-fib pills stay on the right).

07 Position sizer

Fixed-fractional risk model — the same method used by professional discretionary traders. You set your account balance and risk tolerance; the sizer computes how many shares to buy per entry.

The math

position_size = (account_balance × risk_pct) ÷ (entry_price − stop_loss)

Example:

• Account: $10,000
• Risk per trade: 1% = $100
• Entry (E1): $28.50
• Stop: $28.25
• Risk per share = $0.25
• Position size = $100 ÷ $0.25 = 400 shares

08 Sim Trade

Test what would happen if you took the current setup. Two buttons: SIM AUTO walks the analyzer's setup forward through candles; SIM MANUAL does the same for your drawn fib.

What the sim is doing

1. Computes E1, E2, E3, SL, TP1, TP2, TP3 from the active setup (auto or manual).
2. Walks candle data forward from the setup's anchor point.
3. For each entry, checks whether price reached the entry level — if yes, marks it filled.
4. For each filled entry, walks further forward and checks SL or TP1/TP2/TP3 hit first.
5. Multiplies (price P&L) × (your computed position size) to get dollar P&L per entry.
6. Pushes the result into a log card with a colored AUTO or MANUAL badge.

09 Bot vs You — lifetime leaderboard

Every sim trade updates a running total stored on your device. AUTO totals (the bot's setups) sit next to MANUAL totals (your setups). Over time, you'll get hard data on whether your eye beats the analyzer.
