Convert a Trading View Pine Script a MT5 Expert Adviser (EA)

Hi,

I need to convert the Open Close Cross Strategy R5.1 from Tradingview Pine Script to Meta Trader5 EA, so that it can open and close orders on its own.

Here is the original code:

//@version=3
//
 
strategy(title = "Open Close Cross Strategy R5.1 revised by JustUncleL", shorttitle = "OCC Strategy R5.1", overlay = true, 
  pyramiding = 0, default_qty_type = strategy.percent_of_equity, default_qty_value = 10, calc_on_every_tick=false)
 
//
// Revision:        5
// Original Author: @JayRogers
// Revision Author: JustUncleL revisions 3, 4, 5
//
// *** USE AT YOUR OWN RISK ***
//  - There are drawing/painting issues in pinescript when working across resolutions/timeframes that I simply
//    cannot fix here.. I will not be putting any further effort into developing this until such a time when
//    workarounds become available. 
//    NOTE: Re-painting has been observed infrequently with default settings and seems OK up to Alternate 
//          multiplier of 5.
//          Non-repainting mode is available by setting "Delay Open/Close MA" to 1 or more, but the reported
//          performance will drop dramatically.
//
// R5.1 Changes by JustUncleL
//  - Upgraded to Version 3 Pinescript.
//  - Added option to select Trade type (Long, Short, Both or None)
//  - Added bar colouring work around patch.
//  - Small code changes to improve efficiency.
//  - NOTE: To enable non-Repainting mode set "Delay Open/Close MA" to 1 or more.
//  9-Aug-2017
//  - Correction on SuperSmooth MA calculation.
//
// R5 Changes by JustUncleL
//  - Corrected cross over calculations, sometimes gave false signals.
//  - Corrected Alternate Time calculation to allow for Daily,Weekly and Monthly charts.
//  - Open Public release.
// R4 Changes By JustUncleL
//  - Change the way the Alternate resolution in selected, use a Multiplier of the base Time Frame instead,
//    this makes it easy to switch between base time frames.
//  - Added TMA and SSMA moving average options. But DEMA is still giving the best results.
//  - Using "calc_on_every_tick=false" ensures results between backtesting and real time are similar.
//  - Added Option to Disable the coloring of the bars.
//  - Updated default settings.
//
// R3 Changes by JustUncleL:
//  - Returned a simplified version of the open/close channel, it shows strength of current trend.
//  - Added Target Profit Option.
//  - Added option to reduce the number of historical bars, overcomes the too many trades limit error.
//  - Simplified the strategy code.
//  - Removed Trailing Stop option, not required and in my opion does not work well in Trading View,
//    it also gives false and unrealistic performance results in backtesting.
//
// R2 Changes:
//  - Simplified and cleaned up plotting, now just shows a Moving Average derived from the average of open/close.
//  - Tried very hard to alleviate painting issues caused by referencing alternate resolution..
//
// Description:
//  - Strategy based around Open-Close Crossovers.
// Setup:
//  - I have generally found that setting the strategy resolution to 3-4x that of the chart you are viewing
//    tends to yield the best results, regardless of which MA option you may choose (if any) BUT can cause
//    a lot of false positives - be aware of this
//  - Don't aim for perfection. Just aim to get a reasonably snug fit with the O-C band, with good runs of
//    green and red.
//  - Option to either use basic open and close series data, or pick your poison with a wide array of MA types.
//  - Optional trailing stop for damage mitigation if desired (can be toggled on/off)
//  - Positions get taken automagically following a crossover - which is why it's better to set the resolution
//    of the script greater than that of your chart, so that the trades get taken sooner rather than later.
//  - If you make use of the stops, be sure to take your time tweaking the values. Cutting it too fine
//    will cost you profits but keep you safer, while letting them loose could lead to more drawdown than you
//    can handle.
//  - To enable non-Repainting mode set "Delay Open/Close MA" to 1 or more.
