Convert Tradingview PineScript v4 Strategy into MQL4 Expert

Hello,

I have a simple pine script that needs to be converted into an EA.

//@version=4
strategy(title="HIGHER HIGH LOWER LOW STRATEGY", shorttitle="HH LL STRATEGY", overlay=true, initial_capital=1000, default_qty_type=strategy.contracts, currency="EUR")


//Higher High or Lower Low Entry Inputs
price = input(close)
LookBack = input(41)
Highest = highest(LookBack)
Lowest = lowest(LookBack)

long = price > Highest[1] 
short = price < Lowest[1]

//Safety Confirmation Inputs - Helps to thin out false breakouts or break downs
length = input(10)
High_Guard = highest(length)
Low_Guard = lowest(length)
length2 = input(1)

long1 = long == 1 and Highest[1] > High_Guard[length2]
short1 = short == 1 and Lowest[1] < Low_Guard[length2]

strategy.entry("Long", strategy.long, when=long1)
strategy.entry("Short", strategy.short, when=short1)

This script should have the following functions:

-Same entries showing up on chart like in TradingView (past ones as well) (then you can check if the mql EA behaves exactly like the pine script above)

-showing entries that are taken by the EA

-Starting capital should be read from account balance, same for currency that is used

-LotSize input - how much I want to use for trades, from 0,01 to 0,1 to 1 (of course I can set 0,3 as well and so on)

-Automatic trade execution (for example -  EA opens long position, after the next signal appears a short position will be opened where the long position is automatically closed and viceversa, only ONE position can be taken)

SourceCode included of course
