Harami Price Action¶
v.3.1.0.0 Built on Strategy Core
Overview¶
Trades the Harami: after a run, a bar stays inside the one before it (the mother bar) - a pause from which the run resumes.
How it trades¶
- A run of Run before the mother bars, then an inside bar within the mother bar (colour by Inside bar color, size up to Max inside size %).
- Optional filters: the mother bar's size, the trend (EMA).
- With Confirmation = Break the entry waits for a break of the mother bar within Confirm within bars; the stop can sit beyond the mother bar.
Parameters¶
| Parameter | Default | What it does |
|---|---|---|
| Signal bar offset (bars) | 0 | Which bar is judged as the inside bar: 0 = the last closed bar; 1 = the one before it, so the entry comes a bar after the pattern. |
| Run before the mother (bars) | 1 | How many bars of rising highs (a long) or falling lows (a short) must lead into the mother bar. 0 = no run asked for - the inside bar's colour alone gives the side, so with 0 Inside bar color must be Strict: with Any nothing gives a side and no pattern is traded. |
| Inside bar color | Strict | Strict: the inside bar of a long is bearish and of a short bullish - the pause against the run -. Any: its colour does not matter. |
| Max inside size (% of mother) | 75 | The largest range the inside bar may have, as a share of the mother bar's. 100 = any bar inside the mother. |
| Mother size filter | Off | Judge the mother bar's high-low range: in ticks, or in ATRs of the bars before it. Off: any size. |
| Min mother size | 0 | The smallest range the mother bar may have, in the unit of Mother size filter. 0 = no minimum. |
| Max mother size | 0 | The largest range the mother bar may have, in the unit of Mother size filter. 0 = no maximum. |
| Size ATR period (bars) | 14 | The ATR the mother bar is measured in, taken on the bar before it. |
| Trend filter | Reversal | The inside bar's close against an EMA. With trend: longs above it, shorts below. Reversal: longs below it, shorts above. Off: no filter. |
| Trend EMA period | 50 | The period of the EMA the trend filter reads. |
| Confirmation | Break | None: the entry is asked for as soon as the pattern is found. Break: only once a later bar closes beyond the mother bar - above its high for a long, below its low for a short. |
| Confirm within (bars) | 3 | How many closed bars after the inside bar the break may take. A pattern not broken by then is dropped. |
| Strategy price | Mother break | The level of the pattern the entry is placed from when the Orders group's Entry price is Strategy. Mother break: the mother bar's high for a long, its low for a short - with a stop entry, the classic inside-bar breakout. Inside break: the inside bar's high or low. Mother mid: the middle of the mother bar - with a limit, a pullback into it. |
| Stop beyond mother (ticks) | 2 | With the Stop loss group's Mode = Strategy: the stop goes this many ticks beyond the mother bar - below its low for a long, above its high for a short. |
