Show HN: Portfolio simulator using trend-following indicators and rebalance API

I've written several comments that all got flagged a GenAI - so here is a quick off-the-cuff version hoping it gets through.

I made this tool because I have long used trend following to protect against market downturns. (Important for those at or near retirement.) There are places like Yahoo Finance where you can use basic trend-folling, but there are no backtests and you need to check the results daily.

This tool has all the backtest results available and I have a Make.com blueprint you can use to alert you to changes.

Enjoy - I hope this actually survives the AI checks....
