I have created an MT5 version. Please download it from post #1.

Please note that the VWAP differs from the MT4 version, as it was difficult to recreate it in the same way for MT5. Instead, it displays three VWAPs: one anchored to the London open, one to the New York open, and one to the Tokyo open.

As for how to use it, this VWAP can be used in the same way as a moving average.

EasyOrder is a customised version of Position Sizer.
I have removed parameters and processes that I personally found unnecessary, so it runs more efficiently. As a result, it would be difficult to restore the full functionality of Position Sizer.
