b_leap
« on: 08 Feb 2015, 23:01 »
Hi,

Quick question...

Is the variable "b_leap" positive or negative if the price moves for example from 6.60 to 6.20?

From reading the manual it seems to suggest that it would be -2 in this case but reading another thread on this forum seems to suggest it would be +2?

Thanks in advance.

manual says "Back price leap (the number of ticks the back price grew by over the last refresh)"

Therefore +2 is correct.

This one has always tied me up in knots as well.  I would say that the answer was -2

In the manual just below the section about b_leap is b_growth, which gives an example:

b_growth for the price change from 4.0 to 4.2 is 0.2. If the price changed from 4.2 to 4.0, then it's -0.2.

To my mind, that indicates that if a price is coming in (or steaming or the odds getting shorter or whatever way you want to describe it), then b_leap, like b_growth, is a negative number.

Just my interpretation, not saying it's correct.

b_leap (ticks)
b_growth (absolute value in dollars)


price change 1.32 to 1.33
b_leap = -1
b_growth = +0.01

thanks for clearing that up Londolozi.

A related question;

If you wanted to know which price had shortened the most over a certain time, would you use
 pdif_{minutes}is the MAXIMUM of all, or pdif_{minutes}is the MIMIMUM of all?

You need to use Excel.
Customcell in cell M1 eg: MAX(M4:M75)
