Update input variables for exit alerts
Adding input for price to exit alerts

This is an alert that stocks is moving outside of normal trading range.
Does not necessarily mean that it is a hard exit on either side but it
is a signal to monitor much more closely.
Defaults are a 21 day RSI SR for a target, and a three day low/high for
a stoploss. If the target is reached, then switch to a 180 day RSI SR,
and a stoploss of a close below/above the previous day. Let profitable
breakouts ride until there's a hint of it stalling out.
