Alexander,

Thanks so much for this. I must have missed the notification and have only just discovered it again. It seems to be popular by the look of the downloads.

I will have a good look later.

By the way, whats happened to Allpin, does he work with you guys anymore?
Are you able to look at any of the coded programs (exe) I have a small problem with the CSV project

Is this your area of skill?

May I ask what is K for ? May I understand that Up bar is a bar which got the close higher than that of a previous bar. It was appreciated if you could explain why using Middle Price in this formula
Thank you

K is a constant set by the user.
Code: Select all
 local D=(source.high[period-1]-source.low[period-1])/K;
Middle=(source.high[period-1]+source.low[period-1])/2;
    local Up=Middle+D;
    local Dn=Middle-D;

or simplified

Up = source.median[period-1] + (source.high[period-1]-source.low[period-1])/K;
Dn = sourcemedian[period-1] - (source.high[period-1]-source.low[period-1])/K;

If price is greater then Up then we will have Up Bar
If price is less then Dn then we will have Bar
otherwise we will have Middle Bar
