Hi need help porting this tos indicator to tradovate. It plots previous day high, low, premarket high, low, and mid

#Plot yesterday’s high / low
input Showchartbubbles = yes;
input ShowTodayOnly = yes;
def Today = if GetDay() == GetLastDay() then 1 else 0;
plot Yhigh = if ShowTodayOnly and !Today then Double.NaN else high(period = “day” )[1];
plot Ylow = if ShowTodayOnly and !Today then Double.NaN else low(period = “day” )[1];

Yhigh.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
Yhigh.SetDefaultColor(Color.UPTICK);
Yhigh.SetLineWeight(2);
Ylow.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
Ylow.SetDefaultColor(Color.DOWNTICK);
Ylow.SetLineWeight(2);

declare once_per_bar;

input PlotPreMktLinesHrsPastOpen = yes;
def bar = BarNumber();

def nan = Double.NaN;
def vHigh = high;
def vLow = low;

def PMhrs = RegularTradingStart (GetYYYYMMDD()) > GetTime();
def RMhrs = RegularTradingStart (GetYYYYMMDD()) < GetTime();
def PMStart = RMhrs[1] and PMhrs;
def PMHigh = CompoundValue(1, if PMStart then vHigh else if PMhrs then Max(vHigh, PMHigh[1]) else PMHigh[1], 0);
def PMLow = CompoundValue(1, if PMStart then vLow else if PMhrs then Min(vLow, PMLow[1]) else PMLow[1], 0);
def highBar = if PMhrs and vHigh == PMHigh then bar else nan;
def lowBar = if PMhrs and vLow == PMLow then bar else nan;
def PMHighBar = if bar == HighestAll(highBar) then PMHigh else PMHighBar[1];
def PMLowBar = if bar == HighestAll(lowBar) then PMLow else PMLowBar[1];

plot PMH = if PlotPreMktLinesHrsPastOpen and PMHighBar != 0
then PMHighBar
else nan;
plot PML = if PlotPreMktLinesHrsPastOpen and PMLowBar != 0
then PMLowBar
else nan;
plot PMMid = if PlotPreMktLinesHrsPastOpen and PMHighBar != 0 and PMLowBar != 0
then (PMHighBar + PMLowBar) / 2
else nan;

AddChartBubble(ShowChartBubbles and bar == HighestAll(highBar),
PMHigh,
“PM High”,
Color.Gray,
1);

AddChartBubble(ShowChartBubbles and bar == HighestAll(lowBar),
PMLow,
“PM Low”,
Color.Gray,
0);

AddChartBubble(ShowChartBubbles and bar == Max(HighestAll(highBar), HighestAll(lowBar)),
(PMHighBar + PMLowBar) / 2,
“PM Mid”,
Color.Gray,
1);

addcloud(pmh, yhigh,Color.light_gray, Color.Light_gray);
AddCloud(pml, ylow, Color.light_gray, Color.Light_gray);
