Alerts logic

[wolffan]

Based on a Coin, we want an alert.

First, choose coin (from available coins) Second choose exchange you want to get the feed info from. Then show the current price and allow to choose an alert price (above or below).

Simple logic, all data we have already. We could also include % margin for more alerts, so alert 15% before price match, 10% and 5%. (just an idea).

We need a db to store the previous price and the new price so we know how the price is fluctuating.

Pretty simple drop down plus UI.

@christianbaroni mentioning you as I'll do this with the stuff I have and then elaborate something
