The chart above shows a 3 minute bar chart of the SPY ETF. It includes a set of 3 MIDAS support curves, followed by a TopFinder curve.
The first S1 curve was launched at the low of the day. 30 mins later it caught the first pullback accurately. From the pullback, we launch a new S2 curve. Price moves up and then returns to retest. From the next pullback, we launch an S3 curve. Additionally, we launch a TopFinder curve, and adjust it to fit the next few bars. Afterward, the closest we come to a pullback is at 7:45. Fit to this low, TopFinder tracks the trend to the correct bar.
Several rectangles have been drawn to illustrate interactions between price and S curves later in the day. The first box shows two bounces off of S3, which is finally broken around 9:30. Price moves down to test S2, but bounces back up and goes through S3.
