There are many indicators that can be used in trading when we perform any activities on an exchange. Now, we don't agree on which of these we want because, for sure, we have indicators that other traders don't want. We may use indicators that are difficult for others to use.
The indicators that are difficult for us to use for others are easily something like that, because for me, the only indicators that I often use are Trendline, SMA, RSI, and Keltner, and nothing else. There is also a chance that I often only use two of the ones I mentioned.
