Hi,

Besides ability of back testing Point and Figure setups, what about Drummond Geometry? Do you have any plan to include it in future release?

I am sure you can create Drummond Geometry charts with the available functions.

Yes, you are right, I just did. I am having difficulty in increasing the size of points. Please look at the following statement:

pl0 = (high+close+low)/3;
pl = (ref(pl0,1)+ref(pl0,2)+ref(pl0,3))/3;
Plot(round(pl,2), "PL", colorRed, ChartPoint, StyleWidth2);

The size of the point was so small that it was almost invisible, how do I increase it? Also, what is the function name for average of a,b,c,d ?

Use this plot like this:
Plot(round(pl,2), "PL", colorRed, ChartPoint, StyleSymbolCircle);

To calculate average of a, b, c and d:
avg1 = (a + b + c + d) / 4;

OK, I would rather write it like this:

pl = TypPrice(high,low,close);
pl = TypPrice(ref(pl,1),ref(pl,2),ref(pl,3));
Plot(round(pl,2), "PL", colorBlue, ChartPoint, StyleSymbolCircle);

Thanks

I have a doubt, I understand what TypPrice(high,low,close) is doing, however, if I use TypPrice(Time period), and try to plot two different lines with time periods as 14, and 22, they just overlap each other, why so? I tried with several different combinations of time periods and could not see any difference.

You should only use the "TypPrice" version with the three parameters:
TypPrice(high,low,close)
