ランドビルダーとは
南アフリカランド/円（ZAR/JPY）専用の複利型EAです。高水準のスワップポイントを収益の柱に、押し目買いと部分決済でコツコツ利益を積み上げます。前作「kotukotu-EX ZARJPY」の後継として、ロジックを全面的に見直し、ナンピン型EA最大の弱点である「暴落時の破綻」への防御機構を3層搭載しました。
特徴1｜危機の年にもプラス（バックテスト実測）
| 年 | 出来事 | 年間損益 |
|---|---|---|
| 2008 | リーマンショック | +28.0万円 |
| 2011 | 欧州債務危機・ランド急落 | +14.1万円 |
| 2020 | コロナショック | +10.9万円 |
| 2024 | 円キャリー巻き戻し | +30.9万円 |
19年間で負け越した年は2012年（-1.6万円）のみ。暴落を「耐える」のではなく、防御機構でポジションを軽くしながら通過する設計です（初期資金100万円・デフォルト設定時）。
特徴2｜3層の暴落防御機構
|
第1層｜ナンピンロット逓減 深い買い増しほどロットを自動縮小。露出の膨張を根本から抑えます。 |
|
第2層｜証拠金レベル3段階ガード 証拠金レベルの低下に応じて「新規停止 → 救済ペア決済 → 最損ポジション決済」を段階実行。ブローカーの強制ロスカットより先に、自らポジションを軽くします。 |
|
第3層｜実効レバレッジ上限 総建玉が有効証拠金の3倍を超える買い増しを自動スキップ。好調期の複利拡大が暴落時の凶器になるのを防ぎます。 |
特徴3｜設定はほぼ不要
戦略の中核パラメータ（ナンピン幅・ロット逓減率・防御機構の閾値など）は、19年の検証で確定した値に内部固定してあります。お客様が決めるのは実質「Risk（複利の強度）」だけ。デフォルトのまま4時間足チャートにセットすれば稼働します。
過剰最適化していない根拠
全取引を2020年で前後に分割し、直近期間でも優位性が保たれるかを検証しました。
| 期間 | プロフィットファクタ |
|---|---|
| 前半 2007〜2019 | 2.90 |
| 後半 2020〜2026 | 3.22 |
直近でもPFが維持〜改善しており、過去に当てただけのカーブフィッティングではないことを確認しています。
基本ロジック
移動平均線で環境を認識し、ボリンジャーバンドの押し目で買いエントリー。上昇時はコツコツ利益を確定し、下落時は間隔・ロットを自動調整しながら買い下がり、スワップを受け取りつつ反発を待ちます。ポジションが増えた局面では「利益の乗った玉＋最も損失の大きい玉」をセットで決済する部分決済ロジックが露出を軽くします。売りは行いません（買い専用・マーチンゲール非使用）。
推奨環境
| 推奨ブローカー | 第一推奨: FXTF／利用可: 楽天証券 楽天MT4（いずれもバックテスト検証済み） FXTFのゼロスプレッド口座が最も有利です（同条件の検証で楽天MT4の成績はFXTFの約3分の2。ただし楽天でも19年全年プラスを確認）。スプレッドの広い口座・海外業者でのご利用は推奨しません。 |
| 推奨証拠金 | 100万円〜（デフォルトRisk=1時） |
| セットする時間足 | H4（4時間足） |
| 稼働環境 | VPS等の24時間稼働環境を推奨 |
設定可能なパラメータ
| パラメータ | 内容 | 初期値 |
|---|---|---|
| MAGIC1 / MAGIC2 | マジックナンバー（他EAと重複不可） | 38762 / 38763 |
| fukuri | 複利モード | true（推奨） |
| Risk | 複利の強度。上げるほどハイリスク・ハイリターン | 1.0（推奨） |
| Lots | 単利モード時の固定ロット | 0.1 |
| Slippage / Max_Spread | 許容スリッページ／許容スプレッド | 50 / 100 |
| Timefilter ほか | 指定時間帯の取引停止 | false |
| UseAlertPopup / UseSendMail | 通知設定 | true / false |

About Forex Automated Trading
What is Forex Automated Trading (MT4 EA)?
Forex Automated Trading refers to trading that is automated through programming, incorporating predetermined trading and settlement rules. There are various methods to conduct automated trading, but at GogoJungle, we deal with Experts Advisors (hereinafter referred to as EA) that operate on a trading platform called MT4.
Trading Types of Forex Automated Trading
There are various types of EAs (Expert Advisors) for different trading types that can be used on MT4.
Just like discretionary trading, there are those that decide trading and settlement timings by combining indicators, those that repeatedly buy or sell at certain price (pips) intervals, and trading methods that utilize market anomalies or temporal features. The variety is as rich as the methods in discretionary trading.
To categorize simply,
・Scalping (Type where trades are completed within a few minutes to a few hours),
・Day Trading (Type where trades are completed within several hours to about a day),
・Swing Trading (Type where trades are conducted over a relatively long period of about 1 day to 1 week)
・Grid/Martingale Trading (Holding multiple positions at equal or unequal intervals and settling all once a profit is made. Those that gradually increase the lot number are called Martingale.)
・Anomaly EA (Mid-price trading, early morning scalping)

Risks, Advantages, and Disadvantages of Forex Automated Trading
When engaging in Forex, there are risks in automated trading just as there are in discretionary trading.
However, a substantial advantage of automated trading is its ability to limit and predict risks beforehand.
[Risk]
Inherent to forex trading are the trading risks that undeniably exist in automated trading as well.
・Lot Size Risk
Increasing the lot size forcibly due to a high winning rate can, in rare instances, depending on the EA, lead to substantial Pips loss when a loss occurs. It is crucial to verify the SL Pips and the number of positions held before operating with an appropriate lot.
・Rapid Market Fluctuation Risk
There are instances where market prices fluctuate rapidly due to index announcements or unforeseen news. System trading does not account for such unpredictable market movements, rendering it incapable of making decisions on whether to settle in advance or abstain from trading. As a countermeasure, utilizing tools that halt the EA based on indicator announcements or the VIX (fear index) is also possible.
[Benefits]
・Operates 24 hours a day
If there is an opportunity, system trading will execute trades on your behalf consistently. It proves to be an extremely convenient tool for those unable to allocate time to trading.
・Trades dispassionately without being swayed by emotions
There is an absence of self-serving rule modifications, a common human tendency, such as increasing the lot size after consecutive losses in discretionary trading or, conversely, hastily securing profits with minimal gains.
・Accessible for beginners
To engage in Forex trading, there is no prerequisite to study; anyone using system trading will achieve the same results.
[Disadvantages]
・Cannot increase trading frequency at will
Since system trading operates based on pre-programmed conditions, depending on the type of EA, it might only execute trades a few times a month.
・Suitability may vary with market conditions
Depending on the trading type of the EA, there are periods more suited to trend trading and periods more suited to contrarian trading, making consistent results across all periods unlikely. While the previous year might have yielded good results, this year's performance might not be as promising, necessitating some level of discretion in determining whether it is an opportune time to operate.

Equipment and Environment Needed for Automated Trading Operation
The requirements for operating automated trading (EA) on MT4 are as follows:
・MT4 (MetaTrader 4. An account needs to be opened with a Forex company that offers MT4.)
・EA (A program for automated trading)
・The operating deposit required to run the EA
・A PC that can run 24 hours or a VPS (Virtual Private Server), where a virtual PC is hosted on a cloud server to run MT4.
・MT4 (MetaTrader 4. An account needs to be opened with a Forex company that offers MT4.)
・EA (A program for automated trading)
・The operating deposit required to run the EA
・A PC that can run 24 hours or a VPS (Virtual Private Server), where a virtual PC is hosted on a cloud server to run MT4.
Installation of MT4 and Account Login
If you open an account with a forex broker that supports MT4, you can use MT4 as provided by that forex broker. MT4 is a stand-alone type of software that needs to be installed on your computer, so you download the program file from the website of the FX company where you opened the account and install it on your computer.
Additionally, there are both demo and real accounts available. You can experience trading with virtual money by applying for a demo account. After opening a real account, you select the connection server assigned by the Forex broker, enter the password, and log in to the account.
When you deposit money into your account using the method specified by the forex broker, the funds will be reflected in your MT4 account, and you can trade.

How to Install EA on MT4
To set up an EA when you purchase it through GogoJungle, follow the steps below:
Firstly, download the purchased EA file from your My Page on GogoJungle. You will download a zip (compressed) file, so right-click to extract it and retrieve the file named ‘◯◯◯ (EA name)_A19GAw09 (any 8 alphanumeric characters).ex4’ from inside.
Next, launch MT4 and navigate to ‘File’ → ‘Open Data Folder’ → ‘MQL4’ → ‘Experts’ folder, and place the ex4 file inside. Once done, close MT4 and restart it. Then, go to the upper menu ‘Tools’ → ‘Options’, and under ‘Expert Advisors’, ensure ‘Allow automated trading’ and ‘Allow DLL imports’ are checked, then press OK to close.
The necessary currency pair and time frame for the correct operation of the EA are specified on the EA sales page. Refer to this information and open the chart of the correct currency pair time frame (e.g., USDJPY5M for a USD/Yen 5-minute chart).
Within the menu navigator, under ‘Expert Advisors’, you will find the EA file name you placed earlier. Click to select it, then drag & drop it directly onto the chart to load the EA. Alternatively, you can double-click the EA name to load it onto the selected chart.
If ‘Authentication Success’ appears in the upper left of the chart, the authentication has been successful. To operate the EA, you need to keep your PC running 24 hours. Therefore, either disable the automatic sleep function or host MT4 on a VPS and operate the EA.

In Case You Want to Change the Account in Use
EAs from GogoJungle can be used with one real account and one demo account per EA.
If you want to use it with an account other than the authenticated one, you need to reset the registered account.
To reset the account, close the MT4 where the Web authentication is registered, then go to My Page on GogoJungle > Use > Digital Contents > the relevant EA > press the ‘Reset’ button for the registration number, and the registered account will be released.
When the account is in a reset state, using the EA with another MT4 account will register a new account.
Also, you can reset the account an unlimited number of times.

About the Size of Trading Lots
In Forex trading, the size of a lot is usually:
1 lot = 100,000 currency units
0.1 lot = 10,000 currency units
0.01 lot = 1,000 currency units
For USD/JPY, 1 lot would mean holding 100,000 dollars.
The margin required to hold lots is determined by the leverage set by the Forex broker.
If the leverage is 25 times, the margin required to hold 10,000 currency units of USD/JPY would be:
10000*109 (※ at a rate of 109 yen per dollar) ÷ 25 = 43,600 yen.
1 lot = 100,000 currency units
0.1 lot = 10,000 currency units
0.01 lot = 1,000 currency units
For USD/JPY, 1 lot would mean holding 100,000 dollars.
The margin required to hold lots is determined by the leverage set by the Forex broker.
