//  Description
//  =============================================================================
//  This script is designed to be used as a template for building new strategies.
//  The framework provide you with a configurable implementation of the entry, exit,
//  stop loss and take profit trailing logic. The user of this script has to copy
//  it and replace the openLongPosition, openShortPosition, closeLongPosition and
//  closeShortPosition variables in the STRATEGY module according to his needs! 
//  
//  -----------------------------------------------------------------------------
//  Disclaimer:
//    1. I am not licensed financial advisors or broker dealer. I do not tell you 
//       when or what to buy or sell. I developed this software which enables you 
//       execute manual or automated trades using TradingView. The 
//       software allows you to set the criteria you want for entering and exiting 
//       trades.
//    2. Do not trade with money you cannot afford to lose.
//    3. I do not guarantee consistent profits or that anyone can make money with no 
//       effort. And I am not selling the holy grail.
//    4. Every system can have winning and losing streaks.
//    5. Money management plays a large role in the results of your trading. For 
//       example: lot size, account size, broker leverage, and broker margin call 
//       rules all have an effect on results. Also, your Take Profit and Stop Loss 
//       settings for individual pair trades and for overall account equity have a 
//       major impact on results. If you are new to trading and do not understand 
//       these items, then I recommend you seek education materials to further your
//       knowledge.
//
//    YOU NEED TO FIND AND USE THE TRADING SYSTEM THAT WORKS BEST FOR YOU AND YOUR 
//    TRADING TOLERANCE.
//
//    I HAVE PROVIDED NOTHING MORE THAN A TOOL WITH OPTIONS FOR YOU TO TRADE WITH THIS PROGRAM ON TRADINGVIEW.
//    
//    I accept suggestions to improve the script.
//    If you encounter any problems I will be happy to share with me.
