[amibroker] Point of Control

2010-06-18 Thread Rob
I'm looking to create my own Point of Control (POC) calculation... I know PlotVAPOverlayA already calculates it, but I can't return the value via AFL (or the standard deviations around that value). So, basically at the very least I need to calculate a 'mode' price for the days price action...

Hi All, I'd like to code an adaptive standard deviation... I think I use the right term. Lets pretend todays first interval is bar one, I'd like to calculate a standard deviation for each bar based on the number of bars we've had so far today. The StdDev() function clearly only takes a fixed

It doesn't give you the same array... it gives you a scalar. (as Bruce mentioned it seems sometimes AFL can see an array has the same value all the way through and treats it as a scalar). --- In amibroker@yahoogroups.com, Yuki Taga yukit...@... wrote: That was exactly my take on it. Wonderful

Rick's right, the IF() can't check and array for true or false... It can only check a number (i.e. a boolean)... So, if you have an array, somehow you have to get it to be a number... If you look in the AmiBroker function definitions it tells you whether you a function returns an array or a

LastValue() does actually return an array... that as progster correctly says is filled with the last value of SourceArray... however, AFL knows this and treats it as a number... i.e. it can be passed to an If() statement... Again, progster is right, LastValue() can look into the future from a

I'm pretty proficient with AFL... but I have to admit that even I get confused on the useage of SetChartBkGradientFill() with PlotOHLC()... I'm wrestling with one of those problems myself right now... can't get it to do what I want for love nor money. If I work it out I'll let you know! ---

You can write your own zoom function - using OLE functions. That way you can supply a start date and end date to display... I admit it's a complex solution... and not perfect. A 'zoom link' functionality has been on the request list for a long time now. However, the OLE option does work... with

Exactly. Folks, What you see on a chart as an angle has little basis in reality. Take any chart, draw a line on it, and then expand the horizontal (time) axis so that half as many bars are shown. The angle changes; it has to. Compounding this ( as reinsley said ) as you change anything,
