Which currency pair and timeframe does the MACD apply to? (Technical Validation Series)

MACDis one of the indicators commonly used.

This time, under conditions like the following,
which currency pairs and timeframes does it work on?we will examine.

We straightforwardly created an EA with a simple logic: buy on a golden cross and sell on a dead cross.

The parameters are the fairly standard MACD(12,26,9).

The blue areas indicate where profits turned positive.
(diagonal sections are unverified)

Among them, the most reasonable was USD/JPY on the 4-hour chart.

The win rate is below 50%, and average winning trades > average losing trades, so it can be considered a trend-following type.
However, this is not at a level one would actually want to trade, so two filters suitable for trend following were added.

Although the number of trades drastically decreased,
the recovery factor is about 18
and an upward-sloping EA was easily created.

To conclude...

MACD should be used on the USD/JPY 4-hour chart!

I hope this is helpful to you all.
