So what am I missing

Dont subscribe by sending funds straight from an exchange, but list no wallet to use.
Tried the free demo and if I choose to use 2year history and forecast btc the next 2 weeks hourly, I get a forecast that starts at 625, and bounces around 615-690. If I choose to use 5year history I get a forecast that starts at 456 and bounces 450-490.
Please note, Im not throwing shade, I want to try the product out, and profoundly believe this is me missing the obvious and having to note op error once again.
