What indicators have helped you the most and at what time frames you mostly use them? If you have any particular strategy to trade any coin then please share.
Candlestick pattern recognition had helped me a lot. Learning candlestick patterns is also a much easier one compared to any other trading strategies and application of it in real trading is marvelous. You can easily identify the reversal of market using candlestick patterns. But, always relying on only one way of technical analysis is not good. Combining multiple moving averages cross over along with candlesticks help you better.
I recommend to go for 4hr or day charts/timeframe.
Timeframe consideration must be dependent on the way of your trading. If you are into scalping or day-trading then you can go for 30 min or 1 hr charts. But, I am also preferring to use 4hr candlestick patterns as they are filtering out the in-between noise and showing only major trend reversal points.
