VolumeProfile Script Adjustment

Hi everyone,
I'm hoping someone can help me with the current VolumeProfile script I'm using. Currently the only parameters allowed for the "time per profile" values are "Chart, Minute, Minute, Hour, Day, Week, Month, Opt Exp, Bar".

In order to use this profile as part of my Shadow Trader style monkey bar chart, I'd like to add another parameter for "YTD" or possibly longer. Any suggestions would be great - here is the current code:

input pricePerRowHeightMode = {default AUTOMATIC, TICKSIZE, CUSTOM};
input customRowHeight = 1.0;
input timePerProfile = {default CHART, MINUTE, HOUR, DAY, WEEK, MONTH, "OPT EXP", BAR};
input multiplier = 1;
input onExpansion = yes;
input profiles = 1000;
input showPointOfControl = yes;
input showValueArea = yes;
input valueAreaPercent = 70;
input opacity = 50;

def period;
def yyyymmdd = getYyyyMmDd();
def seconds = secondsFromTime(0);
def month = getYear() * 12 + getMonth();
def day_number = daysFromDate(first(yyyymmdd)) + getDayOfWeek(first(yyyymmdd));
def dom = getDayOfMonth(yyyymmdd);
def dow = getDayOfWeek(yyyymmdd - dom + 1);
def expthismonth = (if dow > 5 then 27 else 20) - dow;
def exp_opt = month + (dom > expthismonth);
switch (timePerProfile) {
case CHART:
period = 0;
case MINUTE:
period = floor(seconds / 60 + day_number * 24 * 60);
case HOUR:
period = floor(seconds / 3600 + day_number * 24);
case DAY:
period = countTradingDays(min(first(yyyymmdd), yyyymmdd), yyyymmdd) - 1;
case WEEK:
period = floor(day_number / 7);
case MONTH:
period = floor(month - first(month));
case "OPT EXP":
period = exp_opt - first(exp_opt);
case BAR:
period = barNumber() - 1;
}

def count = CompoundValue(1, if period != period[1] then (count[1] + period - period[1]) % multiplier else count[1], 0);
def cond = count < count[1] + period - period[1];
def height;
switch (pricePerRowHeightMode) {
case AUTOMATIC:
height = PricePerRow.AUTOMATIC;
case TICKSIZE:
height = PricePerRow.TICKSIZE;
case CUSTOM:
height = customRowHeight;
}

profile vol = volumeProfile("startNewProfile" = cond, "onExpansion" = onExpansion, "numberOfProfiles" = profiles, "pricePerRow" = height, "value area percent" = valueAreaPercent);
def con = compoundValue(1, onExpansion, no);
def pc = if IsNaN(vol.getPointOfControl()) and con then pc[1] else vol.getPointOfControl();
def hVA = if IsNaN(vol.getHighestValueArea()) and con then hVA[1] else vol.getHighestValueArea();
def lVA = if IsNaN(vol.getLowestValueArea()) and con then lVA[1] else vol.getLowestValueArea();

def hProfile = if IsNaN(vol.getHighest()) and con then hProfile[1] else vol.getHighest();
def lProfile = if IsNaN(vol.getLowest()) and con then lProfile[1] else vol.getLowest();
def plotsDomain = IsNaN(close) == onExpansion;

plot POC = if plotsDomain then pc else Double.NaN;
plot ProfileHigh = if plotsDomain then hProfile else Double.NaN;
plot ProfileLow = if plotsDomain then lProfile else Double.NaN;
plot VAHigh = if plotsDomain then hVA else Double.NaN;
plot VALow = if plotsDomain then lVA else Double.NaN;

DefineGlobalColor("Profile", GetColor(1));
DefineGlobalColor("Point Of Control", GetColor(5));
DefineGlobalColor("Value Area", GetColor(8));

vol.show(globalColor("Profile"), if showPointOfControl then globalColor("Point Of Control") else color.current, if showValueArea then globalColor("Value Area") else color.current, opacity);
POC.SetDefaultColor(globalColor("Point Of Control"));
POC.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
