Here is my homemade list of terms I use frequently:

Cycles Analysis (CA)
DCL/DCH = Daily Cycle Low/High
ICL/ICH = Intermediate Cycle Low/High (weekly)
YCL/YCH = Yearly Cycle Low/High
HCL/HCH = Half Cycle Low/High (half daily cycle)
LT/RT = Left/Right Translated
KWL/KWH = Kondratieff Wave Low/High
F = Failed
S = Stealth cycle low, i.e. the low was not a confirmed cycle low but price acted afterwards like the low in fact was a cycle low, hence it had to be accepted as a cycle low

Technical Analysis (TA)
BT = BackTest
BO = BreakOut (up/down)
FBO = False BreakOut (up/down)
UL = Undercut Low
OT = OverThrow
ST/LT = Short/Long Term
DB/DT = Double Bottom/Top

H&S = Head & Shoulders
PT/PO = Price Target/Objective
RS = Reverse Symmetry
FS = False Symmetry
PB = PullBack
PD/ND = Positive/Negative Divergence
ATH/ATL = All-Time High/Low
MA = Moving Average
EMA = Exponential Moving Average
GSR = Gold vs Silver Ratio
SGR = Silver vs Gold Ratio
THIN ZONE =  a previous price range with very little volume, creating little resistance

My own tools, developed from experience

RBK = Rounded Bottom Kickdown

PM = Precious Metals
PGM = Platinum Group Metals (plat+pall+a few more)
SM = Stock Market

Purple = other patterns / trend lines / arrows

Green = rounded bottom or cup or handle
Brown = gaps
