Sensibull struggles and it struggles a lot. Especially during peak hours, when the trading volume is high and there is a lot of movement in the market, it is unable to handle the pressure. A lot of people are complaining about the lagging charts and slow updates on prices, and they are right. You can feel the pain when you lose money on fixed-profit trades. The BSE indices are not available to trade and you have very limited options. For no apparent reason, the app asks for an update every few days. If you are in the middle of a trade, you cannot proceed without updating the app.
This is very frustrating, especially when you have an open position. Also, the support is good only on select big brokers like Zerodha or AngelOne. A lot of small brokers are not compatible. There is room for improvement.
