Tool version: O!kurra Capital Defense EA 2.00
11.1 The geography of the chart — two tools
Filters (chapter 10) look at market context — they ask “is SAR on my side”, “does MMD show a trend”. That is the perspective of time — what is happening now.
Activation Zones and Target Lines look from a geographic perspective — they ask “is the price in the right place”. Activation zones define where the button is allowed to generate signals at all; target lines — where you close the basket of positions. You operate both straight from the EA panel (chapter 8.5): you click SELL Zone / BUY Zone / Target SELL / Target BUY, and the object appears on the chart.
Common to both:
- Optional — without them the button operates everywhere, and the basket closes via SL/TP/BEa/EG/PT.
- Per direction — separate for SELL and BUY.
- Objects on the chart — you can move them, resize them, tilt them, delete them with the right mouse button.
- “Live” — you add and remove them while the EA is running, without a restart.
| Activation Zones | Target Lines | |
|---|---|---|
| Function | entry gate (where the button may open) | exit gate (where to close the basket) |
| Affects | signal generation | closing existing positions |
| Lives | until expiry (time) | until touched by price or deleted |
Do your first configurations without them — to see how the button behaves “in freedom”.
11.2 Activation Zones — where the button may operate
An Activation Zone is an area on the chart in which the button of a given direction is allowed to generate signals. If price is inside the zone (and the zone has not expired) — the button operates; if outside — the button sleeps.
Two conditions must be met:
- Opt-in per button: the parameter Active only inside Activation Zone = enabled (the button’s Activation & Exits section, chapter 9). Disabled by default — the button ignores zones and operates everywhere.
- Price inside an active zone of the direction: a BUY button needs an active BUY zone containing the current price; a SELL button — a SELL zone.
Positioning of zones relative to price:
- BUY zone — drawn below the current price (“I buy on a pullback down — the zone is the area price will fall into and become attractive for BUY”),
- SELL zone — drawn above the price (mirror image).
How to place one: you click BUY Zone or SELL Zone on the panel — the zone appears automatically with the default dimensions, in the proper position relative to price. You do not draw it with the mouse like a typical object — the EA places it itself. Afterwards you can move it, resize it, tilt it or delete it. You can have multiple zones of one direction at once — it is enough that price is inside any of them.
11.3 Zone shape: Zone (channel) and Line (line with sensitivity)
An activation zone can take one of two shapes (the Shape parameter):
Zone — a zone (price channel). The default shape. It is a price zone of a defined height, measured from the base line (downward for BUY, upward for SELL), horizontal or sloped. Price “is in the zone” when it fits inside that zone. Optionally the zone can be widened by a margin from both edges (the Zone/Line padding parameter — section 11.4). Visually it is a filled area on the chart.
Line — a line with sensitivity. Instead of a band you place a single line (like a Target Line — you can tilt it freely by dragging its ends). The line itself is a “sharp” stroke, but a tolerance of ±N points works around it — and that is what defines how close to the line price must get for the button to consider it “in the zone”. You set this tolerance with the Zone/Line padding parameter (the sensitivity). With the Line shape, set the sensitivity above zero. At zero the EA falls back to a safety tolerance of ±1 point — a hair-width band that price would have to hit perfectly; in practice signals would appear extremely rarely. Sensible work with a line starts from a realistic tolerance (e.g. ±50 points). The tolerance zone is not drawn — you see only the line, while the ±N-point area works “underneath”.
