Can someone help translate this to efs:

its vary basic.. i dont want the old one posted while back:

# thinkorswim, inc. (c) 2008
#

declare lower;

input over_bought = 45.0;
input over_sold = -45.0;
input percentDLength = 3;
input percentKLength = 5;

def min_low = lowest(low, percentKLength);
def max_high = highest(high, percentKLength);
def rel_diff = close - (max_high + min_low)/2;
def diff = max_high - min_low;


def avgrel = expaverage(expaverage(rel_diff, percentDLength), percentDLength);
def avgdiff = expaverage(expaverage(diff, percentDLength), percentDLength);

plot SMI = avgrel/(avgdiff/2)*100;


plot AvgSMI = expaverage(smi, percentDLength);


plot overbought = over_bought;


plot oversold = over_sold;


thanks!

Hi budfoxx,

Test the attached efs. I coded it to practice passing series from efsInternal functions not because I am an expert at this. So it would be good if you test it against a known plot that is correct.

If you are able to do that I would appreciate it if you would let me know what you find since I have no way of knowing if it is plotting the correct curve.

Just as a note, you might find that this plot is very similar (not equal) to a stochastics 5,3,3 plot.
