VSA (Volume Spread Analysis) vs LRA (Locked-in Range Analysis)

Lets compare two cause-effect methods of analysis which help us to make our trading strategy more profitable:

Volume Spread Analysis (abbr. VSA) seeks to establish the cause of price movements, and from the cause, predict the future direction of prices. The ‘cause’ is quite simply the imbalance between supply and demand in the market, which is created by the activity of separate professional operators called "Smart Money".

Locked-in Range Analysis (abbr. LRA) seeks to determine the direction of the prevailing volume of open positions which will allow to join the further profitable price changes for all united market makers called "centralized automated market-making system".

Comparison Table of the two cause-effect methods of market analysis:

One doesn't need horizontal volumes to trade VSA, I don't think such thing even existed when Tom Williams wrote his book. VSA is not only about "volume imbalance of bars", it's about everything. LRA should be compared with Wyckoff's work, because LRA is only a small piece of Wyckoff's logic. Cause-effect is only one of Mr. Wyckoff's laws. Study the work of the master, you will be surprised.
