Mladen, asymetric is just an idea. Mainly i deal with symetric. Please look at pic.
Just I want to edit that, sorry for pic, like i stated i have no good math, i intented to show you what i mean. Please do not misunderstand me
With the latest version (2.06) you have the possibility to have different envelopes. But, source the basic value for bot is the value of the forecaster itself, you can not have asymmetric values the way you drawn them on pictures (same basic value)
I understood but can i get symetric like pic with the lates version?
It is symmetric
Check the values in the data window and you shall see that envelopes are always at the same distance from the forecaster line if the deviation for upper and lower envelope are the same (so, the are symmetric using forecaster values as an axis)
Mladen, i hope i am not making you crazy, sorry...
Now in the latest version i have two envelopes. I want to see second envelope like other's mirror... Please look at pic at left how symetric looks.
Check these lines :
envd = (1-EnvelopesDeviationDown/100)*sum;
They are symmetrical
The symmetricity you are drawing happens when the line is straight. Forecaster value is not a straight line, Envelopes must follow forecast values
Okay Mladen, i see.
One more question please. Can i see envelope lines like two bands of bollinger bands?
Dear Mladen, Mrtools
I attached a pic, my picture is not well since primary school. Just i wanted what i mean. Yellow line is advanced forecater. I drew white line with my hand. Please look at what i need like bollinger, mirror of other envelope.
Without a third value (an axis that would be used to "mirror" the forecaster value, it can not be done. What would be the way to calculate the axis?
