What helps you the most at trading

I used a lot of indicators in the past, but most of them just interpret the price a bit differently. Only price is a fact and it all comes down to how you interpret it and what tools you use to do it.
One of the most important tools for me is MARKET SENTIMENT and I think it's overlooked by most of the traders. There are different ways to find it out, depending on what instruments you trade.
It is not magical in any way but it is great for determining that initial bias.
