Bittrex API 2.0 Sell Strategy PHP Script

I need a sell strategy script written that pulls down current holdings and allows a user to initiate a series of fill-or-kill stop-loss orders during upswings and partial sells during downswings. This script will require a basic GUI and give a user the ability to pull out of the strategy, watch the progress of the strategy, and get a report on the unrealized or realized profit/loss of the strategy with each refresh. There are a specific set of rules to follow during the upswing and during a downswing that will be shared with you during the initial conversation. Please only apply if you have experience with Exchange APIs and understand the basics of sell orders.
