Converting From Mt4 To Mt5

[Merryment]

Can someone pls assist in coding this in Mt5 for 1min timeframe only. Rough sample in Mt4 is below:

//Step1: Bar2 RSI_2(13) was prev abv or equal to 34 but on Bar1 RSI_1(13) now below 34. //RSI is setting 13
if(RSI_2>=34 && RSI_1<34 && W1 != "yes")
{W1="yes";W1_high=barhigh1;W1_low=barlow1;count=0;Repeat_Signal=0;}

//Step2: At d point whr RSI<34 we want to do 2 things:1. Begin to update d Lower low of W1 until price closes above d High of d Lowest - when this happens, it means W2 has been formed. 2. Begin to setup a counter:
if(W1=="yes" && W2!="yes" && barlow1<W1_low)
{W1_high=barhigh1;W1_low=barlow1;

count=count+1;
if(count>=15) {W1="nil";W2="nil";} //Nullifier

//Step3: Whn price closes abv d high of W1's lowest bar then W2 is formed.
if(W1=="yes" && W2!="yes" && barclose1>W1_high{W2="yes";}

//Final step: If W2 is yes, then whenever a Hammer occurs whose Tail is d lowest among d last 3 candles, starting fro itself, then signal an ArrowUp on d chart on bar zero. Except if count is >=15.
Note: THE HAMMER IS A CANDLE WHOSE TAIL IS >= 60% OF ENTIRE LENGTH OF D CANDLE.
if(W2=="yes" && Hammer=="yes" && barlow1<=Lowest && Repeat_Signal<1)
{
Alert(Symbol()," ","Buy");
ArrowBuffer[0] = barlow1 - 0.5 * dPoint;
W1="nil";W2="nil";Repeat_Signal=1;

}
//List of variables:
string W1,W2;
double Repeat_Signal,barlow1,barhigh1,W1_high,W1_low,Lowest,count;
//END
