I strongley suggest that you really don't trust any indicators especially the free ones they can really be missleading and cause you a lot of loss if you follow them aimiessly, i have tried a bunch of them and they didn't lead me anywhere, i recommed that you stick with the old ways and just educate yourself about the trading ways and try to find to make a demo account on any broker that offer you virtual money to test strategies and your ideas before using real money.
If you've tried a lot of indicators and it doesn't get you anywhere, you need to study them again. Because every indicator that exists has a different way of use and you need to understand.
there is nothing wrong with trading using some auxiliary indicators.
Basic knowledge of technical analysis is also very necessary in order to be able to use indicators well and be able to perform analysis without indicators.
