Hey Guys,
was wondering if someone could help me plot todays VWAP only. I've tried adding in the code "showtodayonly" but it still shows the entire thing. Any help would be greatly appreciated. Ill post the default vwap code below.

Code:
input numDevDn = -2.0;
input numDevUp = 2.0;
input timeFrame = {default DAY, WEEK, MONTH};
def cap = getAggregationPeriod();
def errorInAggregation =
timeFrame == timeFrame.DAY and cap >= AggregationPeriod.WEEK or
timeFrame == timeFrame.WEEK and cap >= AggregationPeriod.MONTH;
assert(!errorInAggregation, "timeFrame should be not less than current chart aggregation period");
def yyyyMmDd = getYyyyMmDd();
def periodIndx;
switch (timeFrame) {
case DAY:
periodIndx = yyyyMmDd;
case WEEK:
periodIndx = Floor((daysFromDate(first(yyyyMmDd)) + getDayOfWeek(first(yyyyMmDd))) / 7);
case MONTH:
periodIndx = roundDown(yyyyMmDd / 100, 0);
}
def isPeriodRolled = compoundValue(1, periodIndx != periodIndx[1], yes);
def volumeSum;
def volumeVwapSum;
def volumeVwap2Sum;
if (isPeriodRolled) {
volumeSum = volume;
volumeVwapSum = volume * vwap;
volumeVwap2Sum = volume * Sqr(vwap);
} else {
volumeSum = compoundValue(1, volumeSum[1] + volume, volume);
volumeVwapSum = compoundValue(1, volumeVwapSum[1] + volume * vwap, volume * vwap);
volumeVwap2Sum = compoundValue(1, volumeVwap2Sum[1] + volume * Sqr(vwap), volume * Sqr(vwap));
}
def price = volumeVwapSum / volumeSum;
def deviation = Sqrt(Max(volumeVwap2Sum / volumeSum - Sqr(price), 0));
plot VWAP = price;
plot UpperBand = price + numDevUp * deviation;
plot LowerBand = price + numDevDn * deviation;
VWAP.setDefaultColor(getColor(0));
UpperBand.setDefaultColor(getColor(2));
LowerBand.setDefaultColor(getColor(4))
