Description
The TAC_DIMinus study is a technical indicator which helps identify market tops. Being part of a system described in BC Low's article "Identify the Start of a Trend with DMI", it gives especially strong signals when used in combination with TAC_ADX.
TAC_DIMinus plots three lines, each being the DI- component of the DMI with a certain length; signals are given when the three lines cluster in the bottom of the subgraph. The basic rule of using TAC_DIMinus is finding clusters at or below the basic reference level of 10; when the lowest line reaches level 5, it is supposed a stronger signal. The confirmation of the bearish reversal is suggested when the cluster turns up from level 5.
For stronger signals, use TAC_DIMinus along with TAC_ADX. For double confirmation that a market top is formed, look for TAC_DIMinus clusters in 5..10 range when TAC_ADX turns down from level 90.
