The market always respects support and resistance or breaks out and moves in an up or downtrend.
I urge new trades to learn to draw support resistance with great care and observe the market to see the results for yourself.
Market will always obey support and resistance levels because they are the backbone of market and based on support and resistance levels only market finds its fluctuations. What are all the technical analysis which are focusing on spotting support and resistance levels then those analysis could give us accurate entry and exit signals. Interestingly what all we need is finding where to enter and where to exit and support and resistance analysis provides that exactly but we are all looking for some other things with the help of different strategies by ignoring these.
Moreover with the help of support and resistance based trading we can go for shorting way of trading even with spot markets with the help of stable coins. All you need is, selling your BTC for stablecoins at resistance levels and then buying back BTCs at the support levels.
In my opinion, support and resistance levels work best in the short term. In the long run, there are many risks.
How? You can find out long term support and resistance levels as well. Just the different time-frame will not alter any of risks in support/resistance analysis. There are multiple analysis are available for spotting support and resistance levels and when more than one analysis say about same price zone then that could be interpreted as strong levels.
