Add alerts to a TradingView pinescript indicator and build a backtesting strategy script

Hello, My name is Johnathan :) Thanks for taking the time to read this project description. *** Please Note *** ... this is a priority project, so it must be started and completed today. 16/09/18 ... I'm based on Australia and it is 6:24am here. I would like you to modify an existing TradingView indicator script, and add alerts to it ... based on a simple conditions. The script is currently an oscillator and has a baseline of zero. You will need to modify the indicator to trigger an alert as the oscillator value goes above zero, or below. The second part of this project, is to convert the study into a strategy, suitable for backtesting. Upon completion, I should have two different scripts: 1. The modified pinescript "study" indicator with alerts. 2. A "strategy" version of the indicator capable of backtesting. Thanks for your time, and I look forward to working with you many times in the future. Cheers, Johnathan
