JP Morgan Vix Signal, Can someone modify the tos script to work on intraday, 1min chart

[Gatekeeper]

declare lower;
def vix_data = close("VIX");
plot vix_average = (vix_data / average(vix_data, 30));
plot signal_line = 1.5;
vix_average.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);

There is nothing in the script that limits it to a specific timeframe.
