New Free Buy/Sell Indicator That Actually Works

I found this free indicator that looks pretty solid. It’s mainly for 30min and 1h charts but can also work on 5min if you're careful with support and resistance. Basically, it uses modified MFI settings to generate buy and sell signals. There are also EMAs at 20, 55, and 100 periods, and you can set it to show signals only when the EMAs are aligned bullish or bearish. This could help filter out a lot of the false signals. Plus, it includes Bollinger Bands for extra confirmation. Sounds like a good tool for trading Bitcoin and other cryptos. Anyone else tried it? What do you think?
