To get the best out of any analysis confluence between multiple tools is best because it gives a clear picture of where to possibly set take profit and set a stop loss in case of reversals. For me i Iove support and resistance and so I combine trend lines, moving average, time frame and indicative candle stick making sure my chart is as neat as possible and any signal outside this i avoid it. This keeps my trading discipline in check.
What are your own it can be beneficial to someone else.
I think it depends on the user. everyone has their own preferences for using trading tools. even I've read that there are some traders who don't use it, of course they have their own technique to see the market and analyze it to determine targets and stop losses, therefore we must explore our abilities to find the right technique for ourselves, of course by increasing trading experience and keep a journal
