4 weeks = 20 bars (not 28 as you mention) providing there are no public holidays etc.
If using weekly time frame then they will always start on a Monday (or the next trading day if a public holiday, and end on a Friday (or previous trading day if a public holiday)
By way of example, If using ROC(C,1) in the weekly time frame - It will take the Friday Close (for a week starting Monday) and the Friday close of that week to calculate the ROC. That it, it wont use the Monday and Friday Close of the week.
Run the below in explore mode, and pick a stock and ensure you see what data it drawing, it will give you a good idea on how to achieve what you are looking for. You can also play with Close, Open etc.
TimeFrameSet(inMonthly);
Annual = ROC( C, 12);
sixmonth = ROC (C,6);
threemonth = ROC(C,3);
TimeFrameRestore();
TimeFrameSet (inWeekly);
eightweeks = ROC (C,8);
fourweeks = ROC(C,4);
oneweek = ROC(C,1);
TimeFrameRestore ();
daily = ROC(C,1);
Filter=1;
AddTextColumn (FullName(), "Full Name", 77);
addcolumn ( annual, "Last 12 Months");
addcolumn ( sixmonth, "Last 6 Months");
addcolumn ( threemonth, "Last 3 Months");
addcolumn ( eightweeks, "Last 8 Weeks");
addcolumn ( fourweeks,"Last 4 Weeks");
addcolumn (oneweek, "Last Week");
AddColumn(MA(C,25), "SMA25");
AddColumn(Close, "Close");
addcolumn (daily, "Daily");
