[EquisMetaStock Group] Metastock Fixed Trailing Stop
LossGordonGlad you like the code I
suggested.The "PREV<=0" is to ensure that we only consider an entry
(setting thelatch) when not already set. This check is not strictly
necessary for apseudo binary latch, but where the "PREV<=0" is needed
is when the latch isset to a value that is not binary (i.e. HIGH, ATR(7)
or whatever), and thenit is essential that ONLY the first entry signal is
used to set the latchvalue. If a second or subsequent set signal was
allowed to change the valuethen the usefulness of the latch as a memory
device is destroyed. The downside of storing a variable value (instead of
a fixed value) is that anotherPREV must be added to the
code.Whether you use one, two, or three or more PREV's in a latch will
depend onthe number of exit options you want to consider. The choice is
yours - fromvery simple to very complex.Roy----
