BC Low’s article, “Identify the Start of a Trend with DMI,” Presented several patterns to signal the beginning and ending of trends. Below are the MetaStock formulas for those signals. These are binary formulas that will have a value of zero normally and the value of 1 (one) when the signal is found. They can be used in any of the formula tools. The steps to enter them an exploration are listed below:
To create an Exploration:
1. Select Tools > the Explorer.
2. Click New
3. Enter a name for the exploration
4. Select the Filter tab and enter the formula
5. Click OK to close the exploration editor.
The formulas are:
ADX clusters
Formula for the start of move:
a1:= ADX(3);
a2:= ADX(4);
a3:= ADX(5);
a1 = a2 AND a1 = a3 AND a1 < 30
Formula for the end of a move:
a1:= ADX(3);
a2:= ADX(4);
a3:= ADX(5);
70 < min(a1, min(a2, a3)) AND
cross(0, roc(a1,1,$)) AND
cross(0, roc(a2,1,$)) AND
cross(0, roc(a3,1,$))
+DI clusters
Formula for a market bottom:
p1:= PDI(5);
p2:= PDI(8);
p3:= PDI(14);
mark:= 10 > Max(p1, Max(p2, p3)) AND
5 > Min(p1, Min(p2, p3));
Ref(mark,-1) AND ROC(p1,1,$)>0 AND
ROC(p2,1,$)>0 AND ROC(p3,1,$)>0
Formula for a strong buy:
a1:= ADX(3);
a2:= ADX(4);
a3:= ADX(5);
p1:= PDI(5);
p2:= PDI(8);
p3:= PDI(14);
mark:= 10 > Max(p1, Max(p2, p3)) AND
5 > Min(p1, Min(p2, p3));
70 < min(a1, min(a2, a3)) AND
90 < max(a1, max(a2, a3)) AND
cross(0, roc(a1,1,$)) AND
cross(0, roc(a2,1,$)) AND
cross(0, roc(a3,1,$)) AND
Ref(mark,-1) AND ROC(p1,1,$)>0 AND
ROC(p2,1,$)>0 AND ROC(p3,1,$)>0
-DI clusters:
Formula for a market top:
m1:= PDI(5);
m2:= PDI(8);
m3:= PDI(14);
mark:= 10 > Max(m1, Max(m2, m3)) AND
5 > Min(m1, Min(m2, m3));
Ref(mark,-1) AND ROC(m1,1,$)>0 AND
ROC(m2,1,$)>0 AND ROC(m3,1,$)>0
Formula for a strong sell:
a1:= ADX(3);
a2:= ADX(4);
a3:= ADX(5);
m1:= PDI(5);
m2:= PDI(8);
m3:= PDI(14);
mark:= 10 > Max(m1, Max(m2, m3)) AND
5 > Min(m1, Min(m2, m3));
70 < min(a1, min(a2, a3)) AND
90 < max(a1, max(a2, a3)) AND
cross(0, roc(a1,1,$)) AND
cross(0, roc(a2,1,$)) AND
cross(0, roc(a3,1,$)) AND
Ref(mark,-1) AND ROC(m1,1,$)>0 AND
ROC(m2,1,$)>0 AND ROC(m3,1,$)>0
