ATR based trailing SL for tradingview

I’m looking for a developer with experience in cTrader and cAlgo to create a custom solution that implements a trailing stop-loss functionality for my Forex trading strategy. My broker does not natively support trailing stop-losses and only provides fixed take-profit and stop-loss options. The solution should dynamically adjust the stop-loss based on the ATR (Average True Range) or a user-defined fixed increment, with the ability to configure parameters like multiplier and step size. Ideally, this should integrate seamlessly with cTrader and leverage the cTrader Open API or a custom cBot. Bonus points if it can also integrate with TradingView alerts for semi-automation. Please share your experience with similar projects and provide an estimate of cost and timeline.
