Symmetrical triangle and inverse Bart

Still pretty new to all of this, and any constructive criticism is welcomed and appreciated. I also would like to know if I am using the Fib ext correctly?
...anyway, on the 15 min chart, I see an asymmetrical triangle playing out as well as a possible inverse Bart, and BTC hitting resistance at 50,660-ish level before heading back down to 42000-ish level or lower.
