Can You Read The Studies?

I'm new to trading and not quite good at it, so my apologies for sounding like an idiot. Based on these two charts, can you tell me what studies are at play here? Specifically those arrows on the right side pointing up and down, and that flag that goes from yellow to green. Also getting those numbers on the bottom of the candle sticks would be nice to know. https://preview.redd.it/5kayqcxfnpke1.png?width=391&format=png&auto=webp&s=91642260a5333db3511ff07341e29ebb83f60a90 https://preview.redd.it/kknbcdxfnpke1.png?width=387&format=png&auto=webp&s=91360abd7a2d7a76d583575989f8d3011e4f4d4a
