Dr Alexander Elder Safe Zone

I find Dr Alexander Elder SafeZone indicator very useful in trading with Metastock charting.
I also trade with charts using Easy language and C#, have not been successful in translating Safezone to this other charting.
Can anyone help?

Contact the author, maybe he has a plug-in

This any good ?

This is an adaptation of Dr. Elder's stop based on the following points
that he emphasizes in his book:
(1) you may use the slope of a 22 day EMA to define the trend
(2) SafeZone is not a mechanical gadget to replace independent thought.
(3) Calculate the stops separately for uptrends and downtrends.
(4) The lookback period should not go back beyond the last important
turning point. If the market has
reversed from down to up two weeks ago, then the SafeZone for the
current long trades should not
look back more than 10 trading days.
(5) An important decision is choosing the coefficient for the SafeZone
stop. He says a coefficient
between 2 and 3 provides a margin of safety, but you must research it
on your own market data.
(6) You can add it to almost any trading system, including Triple Screen.
(7) The excel code that Dr. Elder used in his book kept the stop from
declining for 3 days, by which
time either the uptrend resumes or the stop is hit. This code uses a
period of 5. }

Countlng(0), Countshr(0), Avglow(0),
Avghigh(0), Longstop(0), Shortstp(0), Lstop(0), Sstop(0), ii(0),
LBackTmp(0);

{Determine trend by slope of EMA}
MA = xaverage( Price, MALength );

Thanks, will give this a try
