Update 1
I changed the average volume calculation. Rather than using switch and being limited to only looking
back at 2-9 bars average we can look to whatever quantity of bars we want.

Update 2
I also made it so user inputs a more understandable input. Again using a different calculation. Rather than inputing 0.5 if they wanted spike to appear they input 1.5 meaning current candle is 1.5 times larger than the average volume.
