I went ahead and scripted a weekly bar chart, closely following the example given in the plot page in the manual:
Code:
function plotWeekly() {
  set(PLOTNOW);
  vars Price = series(price());
  BarPeriod = 1440;
  TimeFrame = 7;

  if(Bar%7 == 0) {
    plotGraph("weeklyBarRange", 0, priceHigh(),  LINE,     BLUE);
    plotGraph("weeklyBarRange", 0, priceLow(),   LINE|END, BLUE);
    plotGraph("weeklyBarOpen",  0, priceOpen(),  LINE,     BLUE);
    plotGraph("weeklyBarOpen",  2, priceOpen(),  LINE|END, BLUE);
    plotGraph("weeklyBarClose", 0, priceClose(), LINE,     BLUE);
    plotGraph("weeklyBarClose",-2, priceClose(), LINE|END, BLUE);
  }
}

These weekly ranges make it clear to me that only Sopov and the Knockerfellers are going to be swing trading forex.

Although the manual does say:
Quote:
For removing default chart elements such as price candles or equity curves, set their Color to 0.

I can't figure out how to hide the daily bars that show up. Any ideas? Thanks.
