Most supposed trading signals are false as the market remains unpredictable,you could try to establish a signal but definitely it'll only be based on your individual speculations and not 100% correct.
So it's better to study the market yourself and get to look for little patterns if theirs any
Anyone telling you about any trading signals is just based on his or her own observations,so establish yours
A lot of people always tend to see trading signal as false because they think market should be predictable. That is the idea, market is never predictable, you are only trying to anticipate the possibilities of a trend changing and trying to take advantage of it, otherwise, if the indicators are meant to give you 100% correct predictions, there would be no need for stop loss. It all depends on your strategy, how you approach the market, your trading plan as all these are important and of course, without some indicators or at least some price action to be able to put your strategy in place, how will you then have a strategy? Think about it!
