I'm starting my journey, so I know very little, except I consider myself to be of above average intelligence, and have succeeded so far in my professional journey to date...
My observations on trading, especially day trading, after many hundreds of hours of research and coming at it with a fresh mind are:
1. Algos/Bots do not work. at least nothing available to retail. Even if you have a kick **** strategy, it is not possible to time the market and get the SL and TP in the correct places without intervention. or at least, I haven't found a way yet.
2. You definitely need to focus on a few instruments at first, ideally 1. And it needs to have enough volume and volatility / range to make it worthwhile. Indices are perfect for this. Forex seems too tight a range. and individual shares just too susceptible to news events.
3. Indicators are useful (choose one, any one, i don't think it really matters if you choose any of the ones that are known to be solid; MACD, Ichimoku etc), and show possible set ups, but its the candles that you need to master. As the saying goes - "Indicators for show, price action for dough".
So in summary, you need to be in front of your PC, mastering 1 instrument, using an indicator for setups but price action to pull the trigger. Always using TP & SL of course. and yeah, following solid money management techniques - 1:2 sounds great but in reality anything over 1:1 with a better than 50% win rate will suffice - dont get too greedy.
i'll come back in a few months and let you know how it went
