What is Land Builder

A compounding EA dedicated to the South African Rand / Yen (ZAR/JPY). Using high swap points as the main revenue stream, it accumulates profits steadily through dollar-cost averaging and partial profit-taking. As the successor to the previous “kotukotu-EX ZARJPY,” the logic has been completely revised,and three-layer defenses have been added to protect against the major weakness of martingale-style EAs—collapse during crashes.

Feature 1｜Positive even in crisis years (backtest results)

In 19 years, the only loss year was2012 (-16,000 JPY). The design aims to passage through crashes by lightening positions via defense mechanisms (initial capital 1,000,000 JPY, default settings).

Feature 2｜Three-layer crash defense mechanism

Feature 3｜Minimal setup required

Core strategy parameters (Nanpin width, lot reduction rate, defense thresholds, etc.) areinternally fixed based on 19 years of testing. Customers only choose the Risk level (compounding intensity). If you set it at default on a 4-hour chart, it will run.

Reason against over-optimization

All trades were split into earlier and later periods to verify continued edge in recent periods.

PF remains favorable or improving even recently, confirming this is not curve-fitting based on past data.

Basic Logic

Recognize environment with moving averages, enter on pullbacks of Bollinger Bands. In rising markets, steadily take profits; in declines, automatically adjust distance and lot sizes while accumulating on dips and collecting swaps, waiting for a rebound. When positions increase, a partial-close logic sells a “profit-laden lot + the most loss-making lot” together to reduce exposure.No selling (buy-only, no martingale).
