It really depends on you which TA indicators you like to look at and feel more reliable. Not only the indicators matter, but also their input parameters do matter, like MACD(5, 10, 5) looks very different from MACD (31, 50, 5). So there is no hard and fast rule to follow a particular indicator and its settings.
Its your money you want to trade and you have full freedom to choose whatever indicators you feel works for you. If you analyse the historic data you will find that some indicators may very be useful and leading as compared to other indicators in determining the future price and early buy sell signals. But then after a while some other indicator may also take the charge.
My suggestion is don't just follow one indicator and trade. Follow a trading system that combines 2 or 3 indicators will be good. The system should be as such that the first indicator (leading indicator) gives you an early indication, while remaining indicators give you the confirmation (leading indicator) making it less possibility of losses. One important thing while choosing 2 or more indicators is that it should not lead to multi-collinearity which means that 2 indicators giving the same signals in same time. eg: combination of RSI and CCI. These indicators show the same kind of chart narrowing our horizon. So choose any one of them and look for any other indicator.
Also include a volume indicator. Volume is independent of price and hence can gives a better dimension.
Do not include too many indicators in your system which really makes very difficult to make decisions.
