Types and Properties of Graphical Objects

Graphical object type identifiers used with ObjectCreate(), ObjectsDeleteAll() and ObjectType() functions. It can be any of the following values:

Object Type	Value	Description
OBJ_VLINE	0	Vertical line. Uses time part of first coordinate, price is ignored.
OBJ_HLINE	1	Horizontal line. Uses price part of first coordinate, time is ignored.
OBJ_TREND	2	Trend line. Uses 2 coordinates.
OBJ_TRENDBYANGLE	3	Trend by angle. Uses 2 coordinates or 1 coordinate and angle. To set a line angle (OBJPROP_ANGLE property) use ObjectSet() function.
OBJ_REGRESSION	4	Regression. Uses time parts of first 2 coordinates, price parts are ignored.
OBJ_CHANNEL	5	Equidistant channel. Uses 3 coordinates.
OBJ_STDDEVCHANNEL	6	Standard deviation channel. Uses time parts of first two coordinates, price parts are ignored.
OBJ_GANNLINE	7	Gann line. Uses 2 coordinates, but price part of the second coordinate is ignored. To set the ratio between the price and time scales (OBJPROP_SCALE property) use ObjectSet() function.
OBJ_GANNFAN	8	Gann fan. Uses 2 coordinates, but price part of the second coordinate is ignored. To set the ratio between the price and time scales (OBJPROP_SCALE property) use ObjectSet() function.
OBJ_GANNGRID	9	Gann grid. Uses 2 coordinates, but price part of the second coordinate is ignored. To set the ratio between the price and time scales (OBJPROP_SCALE property) use ObjectSet() function.
OBJ_FIBO	10	Fibonacci retracement. Uses 2 coordinates. To set the number of levels (OBJPROP_FIBOLEVELS property) and the values of levels (OBJPROP_FIRSTLEVEL+n property) use ObjectSet() function.
OBJ_FIBOTIMES	11	Fibonacci time zones. Uses 2 coordinates. To set the number of levels (OBJPROP_FIBOLEVELS property) and the values of levels (OBJPROP_FIRSTLEVEL+n property) use ObjectSet() function.
OBJ_FIBOFAN	12	Fibonacci fan. Uses 2 coordinates. To set the number of levels (OBJPROP_FIBOLEVELS property) and the values of levels (OBJPROP_FIRSTLEVEL+n property) use ObjectSet() function.
OBJ_FIBOARC	13	Fibonacci arcs. Uses 2 coordinates. To set the number of levels (OBJPROP_FIBOLEVELS property) and the values of levels (OBJPROP_FIRSTLEVEL+n property) use ObjectSet() function.
OBJ_EXPANSION	14	Fibonacci expansions. Uses 3 coordinates. To set the number of levels (OBJPROP_FIBOLEVELS property) and the values of levels (OBJPROP_FIRSTLEVEL+n property) use ObjectSet() function.
OBJ_FIBOCHANNEL	15	Fibonacci channel. Uses 3 coordinates. To set the number of levels (OBJPROP_FIBOLEVELS property) and the values of levels (OBJPROP_FIRSTLEVEL+n property) use ObjectSet() function.
OBJ_RECTANGLE	16	Rectangle. Uses 2 coordinates.
OBJ_TRIANGLE	17	Triangle. Uses 3 coordinates.
OBJ_ELLIPSE	18	Ellipse. Uses 2 coordinates. To set the ratio between the price and time scales (OBJPROP_SCALE property) use ObjectSet() function.
OBJ_PITCHFORK	19	Andrews pitchfork. Uses 3 coordinates.
OBJ_CYCLES	20	Time rounds (cyclic lines). Uses 2 coordinates.
OBJ_TEXT	21	Text. Uses 1 coordinate. To set the angle of the writing text (OBJPROP_ANGLE parameter) use ObjectSet() fucntion. To modify the text use ObjectSetText() fucntion.
OBJ_ARROW	22	Arrows (symbols). Uses 1 coordinate. To set the symbol code (OBJPROP_ARROWCODE parameter) use ObjectSet() function.
OBJ_LABEL	23	Text label. To set the coordinates in pixels relatively to the angle of connection (OBJPROP_CORNER, OBJPROP_XDISTANCE, OBJPROP_YDISTANCE parameters) use ObjectSet() function. To modify the text use ObjectSetText() fucntion.
