Build me a Algo Trading Software

The software will be tracking numerous stocks selected by us from BSE and NSE (India). The software will be integrated with Kite (The trading platform of Zerodha Brokers). This will be a single-user software. The main task of the software will be to track the upward movement of stocks and make the buy decisions on its own when certain parameters have been met. The software will allow the stocks to move higher until they start dropping when it will instantly sell them (again based on certain parameters).
