I use Trading Router, Tradingview and MT4. Tradingview is best for chart and analyzing, MT4 is best for executing orders. Trading Router connects those two.
I use Tradingview to run strategies, then use MT4/5 to execute order. I use Trading Router to connect Tradingview and MT4/5, so that the Tradingview can send alerts to MT4/5 and MT4/5 execute order.
