Description
Williams Percent Range is a popular technical indicator that falls into the category of indicators called oscillators. It is similar to the Stochastic indicator but it excludes the “smoothing” component and it uses a reversed scale. Traders use the Williams Percent Range indicator to spot overbought and oversold market conditions, which, in most cases, are used to forecast reversals in market trends.

What does this app do?
The Momentum Trader 1 expert advisor (EA) is an automatic trading strategy that makes buying and selling decisions based upon the Williams Percent Range indicator.

Buying Logic
A signal to buy is created when the Williams Percent Range indicator rises above the WPR_Upper_Level, defined by the user in the EA’s properties window. The EA waits until the current chart candle has closed and then creates a buy trade.

Selling Logic
A signal to sell is created when the Williams Percent Range indicator falls below the WPR_Lower_Level, defined by the user in the EA’s properties window. The EA waits until the current chart candle has closed and then creates a sell trade.

Money Management
This EA does not use stops or limits to manage trades. Instead, buy trades are closed when a new sell signal is created, and sell trades are closed when a new buy signal is created. Because the Williams Percent Range indicator is an oscillator, this EA is always either long or short. However, only one trade will be open at a time.
