MoveObject

Moves a point of a chart object to a new position.

Syntax

MoveObject(objectName: string, pointIndex: number, time: number, price: number): boolean

Parameters

• objectName: string - The name of the object to move

• pointIndex: number - The index of the point to move

• time: number - The new time coordinate

• price: number - The new price coordinate

Return Value

Returns boolean - true if the object was moved successfully.

Description

The MoveObject method moves a specific point of a chart object to a new position defined by time and price coordinates. This method works with various object types that have movable points, such as trend lines, rectangles, and Fibonacci tools.

Example

// Move the first point of a trend line
const success1 = this.api.MoveObject(
  "MyTrendLine",
  0, // first point
  1641024000000, // new time
  1.2 // new price
);
console.log(`Move successful: ${success1}`);

// Move both points of a trend line
function moveTrendLine(
  name: string,
  startTime: number,
  startPrice: number,
  endTime: number,
  endPrice: number
): boolean {
  const success1 = this.api.MoveObject(name, 0, startTime, startPrice);
  const success2 = this.api.MoveObject(name, 1, endTime, endPrice);
  return success1 && success2;
}

// Move a rectangle maintaining its shape
function moveRectangle(
  name: string,
  newTime: number,
  newPrice: number
): boolean {
  try {
    // Get current dimensions
    const time1 = this.api.GetObjectNumberProperty(name, ObjProp.OBJPROP_TIME1);
    const time2 = this.api.GetObjectNumberProperty(name, ObjProp.OBJPROP_TIME2);
    const price1 = this.api.GetObjectNumberProperty(
      name,
      ObjProp.OBJPROP_PRICE1
    );
    const price2 = this.api.GetObjectNumberProperty(
      name,
      ObjProp.OBJPROP_PRICE2
    );

    // Calculate offsets
    const timeOffset = time2 - time1;
    const priceOffset = price2 - price1;

    // Move both points maintaining the shape
    const success1 = this.api.MoveObject(name, 0, newTime, newPrice);
    const success2 = this.api.MoveObject(
      name,
      1,
      newTime + timeOffset,
      newPrice + priceOffset
    );

    return success1 && success2;
  } catch (error) {
    console.log("Error moving rectangle:", error.message);
    return false;
  }
}
