What is Fractal Edge Breakout
Fractal Edge Breakout is an approach to entering on the breakout of the nearest meaningful edge of price. The edges come from fractals (local highs/lows), the direction is confirmed by the EMA slope, and the validity of the breakout — by an ATR-based buffer.
The idea is simple: the market often tests local peaks/troughs; when the close goes beyond the edge + a small allowance, the probability of continuation is higher than with a mere touch without allowance.
- A classic fractal is a five-candle pattern: for an upper fractal the central High is above the two neighbors on the left and right; for a lower fractal the central Low is below its neighbors. These points are convenient to use as local resistance/support levels.
How the edge breakout idea works
- Level: an upper fractal provides local resistance (FH — high), a lower one provides support (FL — low).
- Direction: filter by the EMA slope (current value above/below the previous one).
- Confirmation: require the close beyond the level by ATR × multiplier to filter out “taps.”
- Trade: after confirmation, wait for the next candle and enter in the breakout direction.
How it’s implemented in our bot
- For each bar, the presence of an upper/lower fractal is determined.
- Within the K window, the extreme meaningful ones are chosen: the highest FH and the lowest FL.
- EMA and ATR are calculated with the specified periods.
- The EMA slope is checked (up for BUY, down for SELL).
- A candle “quality” filter: the body share to the full range must be ≥ the specified threshold.
- BUY: close above
FH + ATR × multiplier. SELL: belowFL − ATR × multiplier. - Markers are placed on the chart: arrows and BUY/SELL text with the chosen colors.

Parameters and their effect on behavior
| Parameter (as in settings) | Purpose | If you decrease | If you increase |
|---|---|---|---|
| Fractal window (K) | How many recent bars we consider when picking FH/FL | Levels are “fresher,” more signals | Levels are “stronger,” fewer signals |
| EMA period | Sets slope sensitivity | More flips, more signals | Smoother slope, fewer signals |
| ATR period | Basis for the breakout buffer | Buffer is more responsive to the market | Buffer is more stable |
| Breakout × ATR | Minimum allowance beyond the level | Lower threshold, more signals, more noisy ones | Higher threshold, fewer but cleaner |
| Min. body/range | Requirement for a “confident” candle | We allow weak bodies, more signals | We require strong bodies, fewer, cleaner |
| BUY/SELL label text | Text on arrows | — | — |
| BUY/SELL color | Marker styling | — | — |
- Want more signals? Lower K, Breakout × ATR, and Min. body/range, slightly reduce the EMA period.
- Want fewer but more accurate? Raise K, Breakout × ATR, and Min. body/range, increase the EMA period.
Parameter recommendations
- Fractal window (K): 5–7
- EMA: 20
- ATR: 14
- Breakout × ATR: 0.10–0.15
- Min. body/range: 0.40–0.50
- If there are few signals: first reduce K and Breakout × ATR in small steps.
- K: 7–9
- Breakout × ATR: 0.15–0.20
- Why: to filter out typical “taps” around news.
Filter combinations
- Trend-only: EMA slope conditions are already built in; you can strengthen the filter by increasing Breakout × ATR.
- Thin hours: don’t understate Min. body/range — weak candles tend to retrace more often.
- Fast OTC profile: reduce K and EMA, but offset it with a slightly higher Breakout × ATR.

FAQ
Decrease K and Breakout × ATR in small steps (5–10%), then — Min. body/range.
Increase Breakout × ATR and Min. body/range; check if the EMA period isn’t too small.

Summary
- We use fractal edges as levels and enter on a confirmed breakout.
- Direction is set by the EMA slope, breakout validity — by the ATR buffer.
- The “frequency vs quality” balance is tuned via K, Breakout × ATR, Min. body/range, EMA period.
- Start with cautious default settings and your own mini-stats; change parameters one at a time and assess the effect.
