what is the minimum speed of internet required for pi and kite to work , with out lag and uninterrupted?
The loss of live ticks on chart candles is usually due to a drop or interruption in internet connectivity. Even if the internet speed is decent, you could still face hassles while trading if your internet is fluctuating. That said, 2Mbps and above is a good speed for Pi. Also ensure that your hardware configs are good, quad core processors and higher and 3GB of RAM is good to go.
