Hi Kurt,
1) Is the function for energy bars a straightforward multiplication of (h-l)*sqrt(volume) or is it more esoteric?
2) How complicated is the (hidden) function "paraboic2"? Is it similar to the already visible "parabolic" function? If not, then maybe you could allow me to work with the newer one just for this purpose.
It's not quite that simple. This is done on a tick-by-tick basis, so first you have to identify whether the tick was made under positive or negative volume, convert to change in energy, then add to a cumulative count. So although you see one bar there, it's much more like a tick chart than a minute bar. There's probably a way to get a reasonable estimate though, which could be used within a standard chart. Use the bid_volume and ask_volume keywords, which will give you the amount of buying/selling volume in the bar, and merge that together with the net direction change (from previous close), and there's a chance you can come up with something similar.
As for the parabolic2 function, it's very similar to standard parabolics. The reason this stuff is locked up isn't to keep it away from the W59 crowd, but to keep it away from non-W59 people, who could easily come in here, collect all the algorithms, then port them over to other platforms. So if you get to the point where you have figured out the energy part of the equation and need to get into the parabolic2 stuff, send me an email and we'll go from there.
