Ok, so after years of being with Zerodha, I finally decided to give Pi a shot by installing virtual Windows.
First issue, which seems to have been faced by a lot of Pi users, is the Pi splash-screen freezing after logging in; for me, sometimes Pi started working after re-starting it after deleting the .bin contract files but sometimes I'd to reboot the virtual machine to make Pi work.
Second issue I faced early in the morning once I entered the trade was that one or two charts were missing data, showing up as if the present candle is the first candle of the day, even if it actually wasn't. I couldn't locate the Refresh button to sync/reload the candles.
I decided to give Pi a go because I wanted to try to trade from the chart, & that seems like a very good feature, although like I requested Zerodha a few pages ago, it would be nice to be able to modify pending-orders by dragging them within the chart, & it seems like Tradesmartonline have implemented it, although with Spin, I'm not sure if we can enter directly at a specific price in the chart like we can with Pi.
