TradingView Trend Strategy Automation

I need my trend-following idea turned into a fully automated Pine Script strategy on TradingView. The logic is straightforward: entries and exits will be driven solely by moving-average signals, and the finished code has to be robust enough for live trading as well as in-platform back-testing.

Here is what I expect:
• Clean, well-commented Pine Script v5 code that plots the chosen moving averages, executes long/short orders when the crossover criteria are met, and manages position exits with the opposite cross.
• Simple external inputs (MA length, order size, stop/target toggles) so I can quickly tweak parameters without touching the code.
• Realtime alert generation tied to the trade signals, ready for webhook or broker routing.
• A brief explanation of how to import, apply, and test the script inside TradingView.

Delivery will be complete when the strategy behaves exactly as described on a public symbol of my choice and passes a quick walk-forward test I’ll run on screen with you.
