//(c) Wunderbit Trading
//Modified by Mauricio Zuniga - Trade at your own risk
//This script was originally shared on Wunderbit website as a free open source script for the community. (https://www.tradingview.com/u/Wunderbit/)
// 
//WHAT THIS SCRIPT DOES:
//   This is a scalping script originally intended to be used on altorightmic bot trading.
//   This strategy is based on the trend-following momentum indicator. It includes the Money Flow index as an additional point for entry. 
//HOW IT DOES IT:
//   It uses a combination of MACD and MFI indicators to create entry signals.  Parameters for each indicator have been surfaced for user configurability.
//   Take profits are fixed, but stop loss uses ATR configuration to minimize losses and close profitably.
//HOW IS MY VERSION ORIGINAL:
//   I started trying to deploy this script myself in my algorithmic tradingg but ran into some issues which I have tried to address in this version.
//   Delayed Signals : The script has been refactored to use a time frame drop down.  The higher time frame can be run on a faster chart (recommended on one minute chart for fastest signal confirmation and relay to algotrading platform.  
//   Repainting Issues : All indicators have been recoded to use the security function that checks to see if the current calculation is in realtime, if it is, then it uses the previous bar for calculation.
//   If you are still experiencing repainting issues based on intended (or non intended use), please provide a report with screenshot and explanation so I can try to address.
//   Filtering :  I have added to additional filters an ABOVE EMA Filter and a BELOW RSI Filter (both can be turned on and off) 
//   Customizable Long and Clos Messages : This allows someone to use the script for algorithmic trading without having to alter code.  It also means you can use one indicator for all of your different alterts required for your bots.
//HOW TO USE IT:
//   Find a pair with high volatility - I have found it works particularly well with 3L and 3S tokens for crypto. although it the limitation is that confrigurations I have found to work typically have low R/R ratio, but very high win rate and profit factor.
//   Ieally set one minute chart for bots, but you can use other charts for manual trading.  The signal will be delayed by one bar but I have found configurations that still test well.
//   Select a time frame in configuration for your indicator calculations. 
//   I like ot use 5 and 15 minutes for scalping scenarios, but I am interested in hearing back from other community memebers.
//   Optimize your indicator without filters (trendFilter and RSI Filter)
//   Use the TrendFilter and RSI Filter to further refine your signals for entry.
