It's enough to make profits, you don't need to have many strategies before you can make profits. However it is best you always what benefits you the most, my opinion are about things I have done and it worked out great for me. But generally speaking, haven't you heard that a jack of all trades is a master of non. When you keep having many strategy you will not know how to master anyone. For every market conditions, you should have one strategy that you use in trading them which you have already mastered before you make it your one go to strategy. For bull markets, you should have a strategy and for bear market, you should have a strategy. You can can't use the same strategy for trading in this two market and also when the market is trading sideways, have a strategy for that too. Having one strategy for the different markets is better because you can not have different market strategy for one market and think that you are always going to make profits. Have different trading strategies for different markets but limit them to just one, that's all I'm just trying to say based on what I have experienced myself.
