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 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81590&edit=1
