CRF Bollinger

【EA Description】

This EA "CRF Bollinger" is a scalping counter-trend (reverse trading type) EA designed for the 5-minute chart of USD/JPY. It was developed with an assumed spread of approximately 0.6 pips for USD/JPY, thus it is recommended for FX companies with narrow spreads. The EA can hold a maximum of 3 positions from a single position.【Basic Specifications】・The settings are optimized for USDJPY, so there is no advantage for other currency pairs. ・The annual trading frequency is approximately 2,500 times in the 5-minute chart's averaging mode and about 1,500 times in the single position mode. (It does not support charts longer than 15 minutes) ・It operates on both 1-minute and 5-minute charts, but performs better on the 5-minute chart. ・Can operate simultaneously with other EAs. ・Please set the magic number to avoid overlap with other EAs.

You can use the default settings on servers other than ⅛GMT+2 (winter)/+3 (summer).

【Trading Logic】

"CRF Bollinger" uses Bollinger Bands, CCI, RSI, and Fibonacci for counter-trend trading, focusing on selling on retracements and buying on dips. The Ichimoku Kinko Hyo is used for determining long-term trend direction. While it operates counter-trend in the short term, its main feature is trading in line with the long-term trend.

Averaging Trade (holding up to 3 positions)　

You can change the trading days and times in the property settings. To avoid weekend risk, set WeekendClose to "true" and specify the closing time. ⛀Example Settings (Default Settings)RsiPeriod = 14;// RSI period (range 10-100)BollingerBandsPeriod = 30;// Bollinger Bands period (range 10-100)BollingerBandsDeviation = 1;// Bollinger Bands sigma value (range 1-3) Averaging mode ON (1st position 10,000 units, 2nd position 20,000 units, 3rd position 30,000 units) can be changed in property settings. Depending on the timing of the closing, there may be a temporary hedging situation. If you enable averaging mode, please operate on a server that allows hedging. Due to the high number of trades, please ensure to operate with an FX company that has narrow spreads. It will also trade early in the morning Japan time, so there is a possibility of trading under widened spreads. Since it is equipped with a spread filter, please set the spread filter to a slightly wider value than usual to avoid trading when spreads widen.

【About Backtesting】

For accurate backtesting, please conduct it with all ticks. It will operate with only the opening price, but this will result in a simplified backtest. As it is a scalping EA, it has low spread resistance. When spreads are wide, trading costs increase significantly, making it harder to aim for profits.  

Default settings 5-minute chart（TDS variable spread）　

Version 1.02（Continuous entry prevention feature ON）　

Version 1.02 Default Settings（Continuous entry prevention feature OFF）　

In Version 1.02, the following features were implemented. (January 8, 2025)

4. Added logic to prevent continuous entriesIf it is the same bar as the previous one, do not average true (the number of entries decreases) average false5. Added a feature to not trade for a specified number of candlesticksManualEntry = 0;// Resumes automatic trading after a specified number of candlesticks have passed (range 2-500) Disable this feature = 0. If you enter a number greater than 1 in ManualEntry, the positions held will be immediately closed, and no new entries will be made until the specified number of candlesticks has passed. Immediately after setting, the current bar is also counted as 1, so it will be aggregated based on the input value minus 1. Restarting MT4 will reset the internal count, so counting will start over. Example: Set ManualEntry = 40. After 5 hours (20 candlesticks have passed) restart the EA⋲the count will start from 0, and automatic trading will resume after 40 candlesticks have passed after starting MT4. If you restart MT4 over the weekend, please re-enter the correct number after starting it. In the above example, since 20 candlesticks have passed, 40-20=20, meaning you need to reset ManualEntry to 20 after starting. A comment will be displayed in the upper left of the chart screen saying "Automatic trading will resume after X candlesticks have passed." If you restart MT4 after automatic trading resumes, it will not trade for the specified number of times again based on the property settings. To return to automatic trading mode, please reset ManualEntry to 0.
