Ed what does this mean and how can I get the AFL code ...

hi,

these guys at inditraders did some programming, in this thread there is some code:

http://www.inditraders.com/showthread.php?t=1526&highlight=market+profile+Amibroker+kaka

it is nice for charting (on a limited amount of data, e.g. 15 days of 5-min data) but not for backtesting purposes on 2 years of data. I am also not interested in all these letters, just need the value area and the POC. I would think Amibroker could implement this quite easily because PlotVapOverlayA basicly contains the data already from which you can derive the POC and the VA. If you want to solve it in AFL doing it straightforward would require you to step through the entire range of the day with a certain step density and store this data in an array or static array temporarily and derive the POC and VA's from this storage array. To my knowledge AFL is not really suitable for these type of calculations. When you could store this information in smaller subarrays and one could do some sorting and calculations on much smaller subarrays that would make it much faster. Not sure if the Osaka plugin could be used.

regards, Ed

I dreamed about it... I planned to code it in two decades or more up to
my programming skill .
