If you want to elaborate on this "liquidity seeking mechanism" and the links with propensities. I'll make my best to understand. Even though it's purely for recreational purposes. Who knows ?
From the principles, you can simulate it yourself and perhaps really learn something.
Current price is at all times the level where two parties last agreed to make a transaction.
Trading is both directions seeking liquidity for their position changes, for which exchanges (hopefully) are designed to provide in a safe, just and efficient manner.
Rational buyers want to buy low and rational sellers want to sell high.
So if price goes up, it's because buyers can't find enough liquidity at lower prices and need to bid higher in order to get a long position (demand or lack of supply). If price goes down, it's because sellers can't find enough liquidity at higher prices and need to ask lower in order to go short/sell (supply or lack of demand).
When one side have to yield over time/price changes, a trend forms, which is imbalance between demand and supply.
Trend is hindsight analysis telling you demand was stronger (uptrend) or supply was stronger (downtrend) over time/price change.
Of course, a trend might turn on a dime at any time. Even though buyers are bidding higher when price goes up and vica versa for sellers and lower prices, it doesn't mean this behaviour will persist for very long. However, for longer/stable trends, it is observed that they may persist for some more time.
However,
market efficiency is really how well trade transactions are facilitated, which is a big purpose of
market liquidity: The better market liquidity the more volume are traded per time or price level. High volume zones may be
congestion areas: many trades traded at relatively the same prices over high volume and often over some significant time. Volume can also change price action regimes, act as continuation signals and longer timeframe reversal. However, general volume over time is a sign of an efficient market, more trades happening in a zone, thus making price move less in one direction as long as that type of price action regime is dominating.
This can act as a framework for understanding some of what's happening in the market and why. Of course, it's very much easier to classify market behaviour in hindsight than in real-time.
