Which way to drag

The tool has a start point and an end point, so there are two ways to draw the same move. The direction of the trend decides which one you use.

Uptrend: low to high

Price is making higher highs and higher lows, and you are looking for a place to buy.

Drag from the swing low up to the swing high. On gold that is 2,396 up to 2,431, so the tool marks 0 at the bottom and 1 at the top.

You want price to pull back below 0.5, into the discount at 2,396 to 2,413.50. That is where a buyer gets the cheaper half of the move.

Uptrend: drag up, then wait for price to come back under the middle.

Downtrend: high to low
