When a swing trader asks whether a moving average 'works,' we redirect the question. Averages do not generate trades; they describe where price has spent time. Before any entry, we ask three slope questions on the daily chart.
Question one: direction over twenty bars
Plot the 20-period simple average and count how many of the last twenty sessions closed above it. If fewer than twelve, the average is still recovering from a prior decline. Entering on the first touch often means buying into overhead supply.
Question two: separation from price
Measure the gap between the closing price and the average as a percentage of the average itself. Under two percent, the market is coiling; above five percent on a pullback, you may be late. Our workbook uses a simple ruler on printed charts so you build a physical sense of this distance.
Question three: interaction with the 50-period line
When the 20-period sits above the 50-period and both slope upward, pullbacks to the 20 tend to hold in trending Thai large caps. When the 20 crosses below the 50 while still sloping up, treat the next rally as a test, not a confirmation.
Practise marking these three readings on five historical charts before applying them live. The habit matters more than the indicator settings.
