I've been back-testing various trading scripts and strategies on TradingView, and I'm now interested in applying them to real-world trading. I understand that Pine Script allows me to create custom indicators and strategies that can generate automated buy and sell signals. My goal is to develop strategies that will automatically place orders and manage positions based on the predefined conditions. Could you provide guidance on how to transition from back-testing to live trading using Pine Script on the TradingView platform and Fyers platform?
