Draw a straight line segment on the diagram.

Usage:

Draw a line (COND 1, PRICE 1, COND2, PRICE2, Expand), when Cond 1 condition is satisfied, draw a straight line starting point at Price 1 position, and draw a straight line ending point at Price 2 position when Cond2 condition is satisfied, where EXPAND is the extension type.

For example: DRAWLINE (high & gt=HHV (high, 20), high and low & lt=LLV (low, 20), low, 1)

Draw a straight line between the 20-day high and the 20-day low and extend to the right.
