I am somewhat new to Metastock and am runnning into an unusual problem.
I wanted to set up an Exploration to get average volume to ensure I only looked at stocks with >500k shares a day, but was seeing too much skew due to a single volume spike. I looked and looked, but there is no function for median.
Has anyone made a formula to get a median value from an array? I want to get the median volume from athe last 50 days.
Thanks in advance!

Matrim,
Try this in the exploration.
ColumnA
Mov(V,50,S);
Filter {1st Option}
Mov(V,50,S)>500000; {50day Simple Moving Average of the volume is greater than 500k}
Filter {2nd Option}
LLV(Mov(V,50,S),50)>500000; {Lowest value of the 50day SMA of the volume over the last 50 days is greater than 500K}

Thank you for the help, but this still does not address the actual intent of the formula. However, I have since thought about it and wonder if I am being overly stringent.
Even if there is a volume surge on just a couple days, I think having 50+ days should effectively remove the significance of any single day.
I will try this for a while and see if this will minimize the amount of stocks I look at.
