Description:
------------
I tried to do multiple calculations on AAPL chart (closeprice) and always tried to get the last 50 bars. I took nearly 5 seconds for the calculation. The other functions in trader extention are much, much faster.

Just wanted to get a range (Max and Min) from if a stock price is stable

Test script:
---------------
in a very simple for loop of the array data 

I have data from 1980

$maximum = trader_max($highing,50)[$i];
$minimum = trader_min($lowing,50)[$i];

Actual result:
--------------
The result is correct, but the time required is too long
