The main feature is News Lock Fix—a fixed-lot, single-position EA operating on simple interest.

And the automatic avoidance of important indicators around “News Lock,” plus the time-elapsed gradual narrowing of SL/TP width via “Time Compression Risk Management.”
While reducing exposure to sudden movements,ATR×Multiplierprovides a reasonable take-profit/stop-loss,BE（Break-Even）＋Trailingkeeps profits. Entries arealigned via Short-term/Long-term MA×RSIto improve accuracy,Automatic Lot according to Risk%orFixed Lotcan be chosen. It also supports hedging (when broker allows) andscalping to day tradingfor agile operation.

Logic Overview

• Trend × Momentum Fusion：Short-term MA and long-term MA advantages plus RSI thresholds help suppress excessive contrarian/ trend-following bias.

• Exit Rationalization：ATR×Multiplier sets initial SL/TP →width is narrowed stepwise by Rate% as time passesto prevent large unrealized losses or delayed profit-taking.

• Profit Preservation：At a certain unrealized profit,BE activated、and thereafterTrailingis used to raise it.

• Additional Entry (Optional)：When the remaining distance to SL falls below a specified %multiply lot by a factorto press the advantageous position.

• News Lock：Automatically avoids around the defined importance (★/★★/★★★) and the publication windowBefore/After. If needed,positions are automatically closed within the announcement window.

• ATRMultiplier=76：SL/TP width＝ATR×Multiplier（follows market volatility）

• Fast/Slow MA=20 / 60,

  RSI=73,

  Overbought/Oversold=75/36,

  TimeFrame=H1

• RiskPercentage=1%：If Fixed Lot (Fix) is true, compounding is off, so default is simple interest.

• BE：Break-EvenActivation=89pips / Confirm=56pips

• Trailing：22Pips（Profit extension）

• Time Compression：Interval=4080分（約68時間）,Rate=70%（Each step reduces SL/TP width by ×0.7; new feature）

• News：Importance=★★★,Before/After=60/60分,Close Within Window=ON (by default, no new entries 60 minutes before major indicators; if a position exists, forced close; new entries allowed 60 minutes after the indicator)

• Additional Entry：（Optional）SlRatio%reaches,Lot×Multiplierwill be added (default false)

Why News is Dangerous (Market Microstructure)

• Liquidity can thin out in an instant：Order book becomes sparse,spread widens・quotes may jump.

• Price “jumps”：Ticks may be skipped、Stop/Limit orders fill at unexpected prices (slippage).gaps

• Algo’s initial move：Fast algos rush in→fake breaksやwhipsawsになりやすい。

具体的な被害パターン

1. Spread widening例：USDJPYが平常0.2–0.4pips → 指標前後で2–10pips以上。成行/逆指値は即コスト増。

2. Slippage(slippage of) 10 pips on 1 lot (100k) USDJPY = about ¥10,000 of extra loss

3. Gap-fill execution価格が飛んで指値・逆指値が“飛び越え”、希望価格で約定しない。

4. Re-quotes/Order rejection最大許容スリッページを超えて注文エラー→入り直し時はさらに不利。

5. Forced stop-out急変で評価損が急拡大、証拠金維持率が急低下。

6. 誤作動/過剰約定高波形のヒゲで連続約定→すぐ反転して損切りの連鎖。

7. 相関崩れ普段の逆相関/正相関が壊れ、ヘッジが効かない。

8. ブローカー仕様変更「ニュース前はClose Only」「ストップレベル拡大」「証拠金率一時引上げ」等の一時ルールで戦略が崩れる。

よくある勘違い

• 「指標は大きく動く＝儲かる」→方向とタイミングを外すと即死。

• 「SLがあるから大丈夫」→**ギャップでSLが“通過”**し、想定より大きく負ける。

• 「スキャルなら逃げ切れる」→約定遅延＋広スプレッドでエッジが消える。

実務対策（裁量・EA共通）

• 取引停止ウィンドウ：重要度（★/★★/★★★）に応じて発表前後に停止（例：前60分/後60分）。

• 保有整理：発表跨ぎは建玉を軽く、もしくは全クローズ。（デフォルト全決済）

• リスク％縮小：指標日はロット半減や最大損失上限を下げる。

• 逆指値の質：成行SL

• ボラ連動：ATR連動SL/TP、トレーリングで過度な引っ張りを抑制。

• カレンダー整合：タイムゾーン/夏時間ズレに注意（サーバー時刻基準で管理）。

• ブローカー告知：指標日前の一時的ルール変更（証拠金率・最大数量等）を都度確認。

• インフラ：低遅延VPS・安定回線で約定遅延や切断リスクを低減。

NLFix_Gaitame_USDJPY_Ver1.2で落とし穴完全回避！

• Economic Indicator Filter：EconomicFilter=true、重要度はEconomic3(★★★)EfStartTime/EfEndTimeを60–90分

• Time Compression：RiskReductionInterval=1740、RiskReductionRate=80でlong-term holding risk reduction。

• BE/TS：EnableBreakEven/EnableTrailingStop=trueでprofitization of unrealized gainsを自動化。

• Additional Entry：AddEntryはnews week OFF推奨。（Default OFF）

Economic news is more about execution quality risk than direction, and it is a event where losses can be dramatic. By embedding pre-stop, scaling down, and retreat rules into the system, you can automatically enforce “do not enter, let it run, exit quickly,” reducing drawdown frequency and depth at the same time.

Conclusion

MT5 has an official economic calendar API built in, while MT4 lacks an official API and relies on external sources, making implementation and maintenance difficult—this is the essence of the difference.── This is the core difference.

What’s different?

MT5 (easier)

• Official API：CalendarValueHistory / CalendarEventById / CalendarCountriesなどでimportance・currency・timeを直接取得

• Time alignment：server time with DSTを端末側で整合済み

• Filtering：Importance（★/★★/★★★）、before/after windowなどをコードで即フィルタ

• Maintainability：データ源がofficial・consistent formatなので壊れにくい

Why MT4 makes news avoidance difficult

• No official API：WebRequest＋external sitesや独自CSV/インジに依存

• Configuration reliance：WebRequestにはmanually register allowed URLsが必要、環境で失敗しがち

• Formats vary：JSON/HTML/CSV variations→パーサー実装・破損対応が必要

• Time offset：server time, local, UTC, DSTの補正を自前実装

• Reliability：rate limits・changes・downtimeで即死、保守コスト大

Practical Impact

• Implementation time：MT5 requires only a few dozen lines, MT4 requires retrieval, parsing, and time-zone corrections

• Stability：MT5 isrobust／MT4 isprone to break with external changes

• Reproducibility：MT5 makes it easier toreproduce the same judgmentsin backtests and live trading

Notes: If doing this on MT4

• Manual calendar stoppage for key events（EA flag）

• When integrating external indicators/scripts, enforce URL permissions, DST corrections, and exception handling strictly・

• As an alternative, use volatility indicators (e.g., ATR) for automatic stoppagein combination。

In short,MT5 is designed to connect directly to official data, making it simple and robust,MT4 requires aggregating external sources and is fragile, which is the crux of the difference.
