I've searched the forums and haven't found anything like the VWAP Trading Strategy that Easycators has for sale and wondered if we have any of the components already created before I roll up my sleeves and have a go at a similar one... It is almost identical to what I had been envisioning before I stumbled across a video today... I am primarily interested in a lower study similar to his as well as the scan and watchlist column... I'm sure I can write what I want but don't want to reinvent the wheel from scratch if I don't have to... Any input would be greatly appreciated...

If I'm not too tired this evening I'd like to start scripting... I like having multiple trading systems at my disposal and have been playing with VWAP in recent days, comparing it to other indicators and systems that I currently employ... I have already modified the Acrylic VWAP Study to have multiple deviations and it seems to work to my liking...

Here are links to his YouTube Video and his Z-Score Distance From VWAP system for anyone not familiar with what I am talking about...

@rad14733 Done. How is it different? I didn't get a chance to dive in on the video, but I thought they look the same.

Also, here is another VWAP script called V-Score. Hopefully that helps.

Thanks, BenTen... Yes, I have also seen that script and video... Both the code by Mobius and TOS Indicators gives ideas to work from but I need to add some additional bells and whistles... I'll plug away at it but I'm in no rush...

Very anxious to see what you come up with. Tempted to do it myself as well as I like this idea for trading, but I'll wait for your undoubtedly superior product to what I'd make.

In case you haven't thought of it, you might want to start with the bollinger band code and just change the middle line to be VWAP, then add additional outside lines for different deviations away from vwap. At least, that's how I'd do it, but I'm pretty new to coding.

@TraderKevin Thanks for the comments... I'm actually taking ideas from several different scripts and adding in some useful features... One item that I am currently testing is clipping extremes to maintain scale of the lower indicator... I'm not as concerned about how far the extremes go, just that they have reached my maximum intended levels... I am most interested in 1 - 2 deviations and currently have clipping limits set at 3 deviations but will be making the deviation levels user-adjustable...

I am including an image of a very rough first draft that needs a lot more work... As you can see, when the Zscore line reaches +3 it is clipped and flat-lines along the top... For my needs I don't need to see if it spikes to 4 or 5 deviations, just that it has reached my preferred maximum... I may include the ability to turn clipping off however...

Looks like a good start! The clipping is a good feature. Personally, I will probably only use the indicator on the chart itself, rather than a lower study... that way I can see more directly when price reaches certain levels and never lose focus on what matters most: price action.

For anyone interested, I went ahead and edited the built in VWAP study to include plots of 3 different standard deviations from VWAP, as seen in the OP's video. The 3 standard deviation band seems incredibly strong, as one would expect, though it's rarely touched.

Code:
input numDevDn = -1.0;
input numDevUp = 1.0;
input numDevDn2 = -2.0;
input numDevUp2 = 2.0;
input numDevDn3 = -3.0;
input numDevUp3 = 3.0;
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;
plot UpperBand2 = price + numDevUp2 * deviation;
plot LowerBand2 = price + numDevDn2 * deviation;
plot UpperBand3 = price + numDevUp3 * deviation;
plot LowerBand3 = price + numDevDn3 * deviation;

VWAP.setDefaultColor(Color.CYAN);
UpperBand.setDefaultColor(Color.LIGHT_GRAY);
LowerBand.setDefaultColor(Color.LIGHT_GRAY);
UpperBand2.setDefaultColor(Color.RED);
LowerBand2.setDefaultColor(Color.LIGHT_GREEN);
UpperBand3.setDefaultColor(Color.DARK_RED);
LowerBand3.setDefaultColor(Color.DARK_GREEN);
