Hi guys, i want convert some pine Script indicator code to MQL4 but im beginner in MQL pls help me that is some code i want use it in MQL but i dont know how ... `

float p=0
float q=0
float m=0
T=close-open
L=high-low
k=math.abs(T)/(L)
atr=ta.atr(50)
s=(high-math.max(close,open))/(math.min(close,open)-low)

if high[2]>high[1] and high[2]>high[0] and high[2]>high[3] and high[2]>high[4] and close<open and close[1]<open[1] and close[3]>open[3] and close[4]>open[4] and low<low[4] 
    p:=1000*(-1+high[2]/math.min(low[1],low[0]))
else if low[2]<low[1] and low[2]<low[0] and low[2]<low[3] and low[2]<low[4] and close>open and close[1]>open[1] and close[3]<open[3] and close[4]<open[4] and high>high[4] 
    p:=1000*(-1+low[2]/math.max(high[1],high[0]))
else
    p:=0
