There are many similar videos on the Youtube channel and while you think it's the right move with a level of accuracy that can generate constant profits, how was your experience trying it and whether it has been done? Indicators might be able to help your trading but still you can't always rely on it because at certain times the strategy may have to be changed. If the indicators can run the same, then from the past until now people will use the same indicators in trading.

It's a good idea to also have your own trading experience using small capital by trying to combine other people's indicators with your strategy, so you can study or be able to assess one indicator with another. Strategies are not always the same and depend on how market conditions work and there are times when you have to change the strategy in trading.
