GhumeliaPiyush/BTCUSD_Delta_india — reverse-engineered prompt

Build me a simple Python desktop app that watches the BTCUSD pair on Delta Exchange India and gives me clear trading signals in plain English, like Enter Long, Enter Short, and Exit Position. I want it to pull live or recent market data, let me pick a time frame from a dropdown with 5 minutes as the default, and use a mix of EMA, Parabolic SAR, and Stochastic Oscillator to decide what signal to show.

Please make the interface clean and beginner friendly, with a Start button and an obvious place to see the current recommendation. I also want desktop notifications whenever a new signal appears so I do not have to keep staring at the window. If possible, make it keep checking in the background at intervals based on the selected time frame.

This is for learning and study, not automated trading, so focus on reliability and easy setup. If anything is unclear, look up the current Delta Exchange India docs online.
