Wyckoff Accumulation Schematic

Preliminary Support (PS) - We see small signs of increasing number of up bars with spread increasing a little more compared to prior retrace in the down move
Selling Climax (SC): Widening spread and selling pressure usually climaxes and heavy or panicky selling by the public is being absorbed by larger professional interests at or near a bottom. Often price will close well off the low in a SC, reflecting the buying by these large interests
Automatic Rally (AR): This occurs because intense selling pressure has greatly diminished (see lower spread and volume after the SC). A wave of buying easily pushes prices up (Spread widens), bigger retrace compared to the entire down move.
Secondary Test (ST): Testing near the SC area (sometimes above, sometimes below). I interpret ST's purpose is to start creating a liquidity pool.
Spring: Main purpose is to grab liquidity pool (Stop hunt)

Approaching the SC-AR range, pay attention to the volume. Buyer's interest vs Seller's interest (i.e: Increasing Volume on up bars, decreasing volume on down bars)

Normal Volume vs Spread:
- Big spread with high volume (interest to move)
- Small spread with low volume (lack of interest)

Anomalies:
- Big spread with low volume (fake move)
- Small spread with high volume (absorption)

Things to note:
- Spring: Must take out liquidity (equal lows)
- For a healthy uptrend: Up moves should be supported by increasing volume. Down moves should have decreasing volume (lack of supply)
