//
// Description (From Hucklekiwi Pip)
// 
//   The HLHB System simply aims to catch short-term forex trends.
//   It is patterned after the Amazing Crossover System that Robopip once backtested.
//   In fact, it was one of his highest-scoring mechanical systems in 2014! 
//   The system can be applied to any pair, but since I’m into major pairs, 
//   I’m applying it to the 1-hour charts of EUR/USD and GBP/USD.
// -----------------------------------------------------------------------------
// STRATEGY REQUIREMENTS
// -----------------------------------------------------------------------------
//
// Setup
// -----
//  - EUR/USD 1-hour chart
//  - GBP/USD 1-hour chart
//  - 5 EMA: blue line
//  - 10 EMA: red line
//  - RSI (10) applied to the median price (HL/2)
//  - ADX (14)
//
// Entry
// -----
//  - BUY when the 5 EMA crosses above the 10 EMA from underneath and the RSI 
//    crosses above the 50.0 mark from the bottom.
//  - SELL when the 5 EMA crosses below the 10 EMA from the top and the RSI 
//    crosses below the 50.0 mark from the top.
//  - Make sure that the RSI did cross 50.0 from the top or bottom and not just 
//    ranging tightly around the level.
//  - ADX > 25 for Buy and Sells
//
// Exit
// ----
//  - Use a 50-pip trailing stop and a 200-pip profit target. This increases the 
//    chances of the system riding longer trends.
//  - Close the trade when a new signal materializes.
//  - Close all trades by the end of the week.
