Re: EL Help

[Bob Fulks <bfulks@xxxxxxxxxxxx>]

I think I would use an array. The code below uses two arrays, one to store the values of the swinghighs and one to store the bar numbers of the swinghighs. (Alternately, you could only store the bar numbers if you wanted and retrieve the values when you needed them.)

If you only need three values, it is probably easier to move the old values in the array. (Alternately you could use a ring buffer.)

Keep in mind that the swinghighs are only known after "strength" bars have passed so have a lag, by definition.

Sample code (not verified):

Value1 = SwingHigh(1, H, Strength, Strength + 1);

if Value1 > 0 then begin   {If a swinghigh}
   VArray[3] = VArray[2];  {Move old values in the array}
   VArray[2] = VArray[1];
   VArray[1] = Value1;     {Load new swinghigh}
   BArray[3] = BArray[2];  {Move old values in the array}
   BArray[2] = BArray[1];
   BArray[1] = CurrentBar - Strength;  {Load BarNumber of swinghigh}
end;
