I'm trying to create a linear regression MTF but have a problem with plotting the upper and lower lines. Any help would be greatly appreciate.

Code:
``````def fourHours = close(period = AggregationPeriod.FOUR_HOURS);
def day = close(period = AggregationPeriod.DAY);
def week = close(period = AggregationPeriod.WEEK);
def month = close(period = AggregationPeriod.MONTH);
def period=yes;

plot data=close;

input price = close;
input deviations = .8;

input length = 200; #set your channel lookback period here.
input opacity = 50;

def regression = InertiaAll(price, length);
def stdDeviation = StDevAll(price, length);

plot UpperLine = regression + deviations * stdDeviation;
plot LowerLine = regression - deviations * stdDeviation;
def dayreg=InertiaAll(price-day[1],length);
def daysd= StDevAll(price-day[1],length);

plot dayupper=dayreg+deviations*daysd;``````

you can just add this study how many ever times you need it
the Week,Day,Hr,Min is configurable through the menu
remember your chart agreggation must be equal to or smaller than what ever timeframe you choose to configure the script for
