Grid Rash EURUSD

【Basic Specifications】

This is a scalping counter-trend (contrarian) EA that supports EURUSD 1-minute, 5-minute, 15-minute, and 60-minute charts. It was developed assuming a spread of about 0.6 pips on EURUSD, so a broker with a narrow spread is recommended. It can hold up to 3 positions per account.
・Settings are optimized for EURUSD; other currency pairs do not have an edge. ・Annual trading frequency is about 5,000 times in 1-minute chart in Nampin mode and about 3,000 times in One Position mode. About 4,000 times in 5-minute chart in Nampin mode and about 2,500 times in One Position mode. ・Operates on 1-minute, 5-minute, 15-minute, and 60-minute charts. (15-minute and 60-minute chart support in Ver 2.01) ・Can operate concurrently with other EAs. ・Set the magic number to avoid overlapping with other EAs。

※ It can be used with default settings on servers other than GMT+2 (winter)/+3 (summer).

【Trading Logic】

There are times when trading is easier during high-volatility periods (especially when European and US markets are active in the Japanese time in the evening to late night). To measure trend strength, the EA uses ADX (Average Directional Index). ADX calculation period is set to 40 candles; generally, an ADX value of 25 or more indicates a strong trend. (Default setting ADXPeriod = 40) ADXThreshold, the base value for judging trend strength, is set to 15. Also, in the entry trigger key-foot logic, GridSize is set to 0.05 by default (＝5 pips), and a contrarian signal lights up when price moves 5 pips against the trend. Therefore, it is essentially a counter-trend (contrarian) EA that enters in the opposite direction of the trend. It can hold up to 3 positions in average. All positions are closed when the opposite trading signal appears. After closing positions, new entries are made in the direction of the next signal.

Trading days and times can be changed in the properties.

If you want to avoid weekend risk, set WeekendClose to “true” and specify the closing time.

■ Settings Example (Default) ADXPeriod = 40 GridSize = 0.05 (5 pips) ADXThreshold = 15 Trend strength threshold Nampin mode ON (1st position 10,000 units, 2nd position 20,000 units, 3rd position 30,000 units) adjustable via property settings Depending on the exit timing, it may temporarily have hedged positions. If you enable Nampin mode, operate on a server that allows hedging. Because the number of trades is high, use with a broker that offers narrow spreads. Since trades can occur in the early Japan time morning, there is a possibility of trading when spreads are wider. A spread filter is installed, so when spreads widen, do not trade; set the spread filter slightly wider than normal.

【Differences by Timeframe】Basically, it behaves similarly on any timeframe. There are slight differences in volatility and trend judgment by timeframe, so entry points may shift slightly.

【Backtesting】

Backtesting should be performed on all ticks. It is designed not to enter on the open price only.Because it is a scalping EA, spread tolerance is low. If spreads are wide, trading costs increase and it becomes difficult to target profit.

【Description of latest version】

Awakening mode (100% win rate) semi-discretionary trading oriented mode implemented. (May 9, 2025) In Ver 2.01, added a setting to settle profit without stop-loss.When awakening mode is true, it becomes a one-position mode with no stop-loss and no hedging. When awakening mode is on, if positions do not return to the profit-taking line, the EA will not close positions by itself until manual settlement. If you think the rate will not return, please manually settle the positions.

　When awakening mode is on (semi-discretionary trading)　

This mode is designed for semi-discretionary trading with manual settlement in mind. The EA will only handle entries and profit-taking settlements. Hedging or stop-loss can be performed as needed. Manually hedged positions cannot be settled by the EA. Be sure to manually settle any hedged positions when entering opposite trades.

 ■ Favorable marketBecause it is contrarian, it is basically strong in ranging markets. It performs well in markets with high volatility and swings.■ Unfavorable marketMarkets with a one-way, steep, and sharp trend. Examples: Bank of Japan intervention in FX, surprises in US economic indicators, remarks from prominent figures.

USDJPY 1-minute chart（spread 0.3 pips）　

I do not trade USDJPY, but the win rate exceeds 60%, so with proper stop-loss, I think it can be profitable even on USDJPY. Since this is a steady-wins type EA, the win rate should not fall below 60%. If you can avoid big losses in semi-discretionary mode, USDJPY could be profitable.

◇ Recommended accounts ◇ When operating, choose accounts with narrow spreads to improve win rate. Target is 0.5 pips or less. ■ FXTF (Golden Wave Japan) Regular spread: from 0.3 pips～ Fast execution and stability, suited for scalping (scalping allowed as of 2025-04-15 regulatory change) ■ Gaitame Finest Regular spread: from 0.2 pips～ Fast execution and stability, scalping allowed
