Not only you, but I also always make the support and resistance indicators mandatory when making purchase entries. With its easy-to-understand nature, it will always be mandatory for traders to implement it. Not only support and resistance, I also always combine it with Bollinger Bands and Zig Zag.
^ You may use all indicators that you may want as long as you should stick to one plan. It is better to have different preferences so that there is a comparison in your trading preferences and choose the good one. Many people think that trading is very easy to make money but in fact, it is not. There are too many tools and indicators to be used and if you are using all of them just wanted to be sure of your trading activity, you may be confused also which is a better one. Just stick on your own and stop-loss should always be there.
