[amibroker] Re: Compacting IF statements and variable assignments

["gp_sydney" <gp.investment@xxxxxxxxx>]

If the rank values are all as regular as the ones shown, then a
single-line formula would do it as already indicated. However, if they
aren't all regular and can't easily be calculated by a single
equation, then a switch/case statement should be more efficient than a
pile of "if" statements, although not a lot shorter to write:

Buy = False;
switch (A) {
    case 0:
        Buy = Rank < 0; break;
    case 1:
        Buy = Rank >=0  AND  Rank < 60; break;
     ...
    case 100:
        Buy = etc...; break;
    }

Regards,
GP
