Choosing an app to trade is really important, but I encourage everyone to use the Binance app. It's one of the coolest apps, with full updates and giving us trade on the best features. In the Binance app, you will have the necessary indicators like MACD, RSI and EMA available. then you will be very easy to identify a good time to open order. Frankly, I only use my phone to trade and rarely use Tradingview or MT4 to draw trendlines.
