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. |
