Important:
Please adjust the time settings for each indicator.

My trading environment is as follows:
The MT4 server is set to GMT+2 (winter).
02:00 server time (winter) corresponds to 09:00 Japan time.
09:00 Japan time is the Tokyo market open.

During summer time, manual adjustment is required as follows:
03:00 server time (summer) corresponds to 09:00 Japan time.
09:00 Japan time is the Tokyo market open.

Subjectivity in identifying the pullback low:
The pullback low and the most recent low may be interpreted differently by each trader.
Therefore, results may be significantly affected. Please be aware of this.

Other
In order to maintain a consistent sense of daily volatility, the price scale is fixed.
The “PriceScaleFixed” indicator fixes the price scale at approximately 1,500 yen.
It can be adjusted by dragging within the price scale area.

Important Notes
The definitions of a pullback low and a recent low have not been specified.
These are based on my personal discretion and market feel. As this may affect reproducibility, you should clearly define these terms yourself, conduct thorough backtesting, and verify the results before using this strategy.
At present, the approach appears promising; however, statistical validation remains insufficient.
Please ensure you perform your own backtesting and verification prior to implementation.
