Relative Liquidity Changes occur in an instrument when individual market participants place large limit orders at a single price level in the orderbook.
Significant relative liquidity changes in the orderbook suggest a high interest in a big market player at a price level that can attract prices or act as support/resistance.
Relative Liquidity Changes are visually represented at price levels and times when the defined relative liquidity size is reached or exceeded. Here, one market player places 300 lots in the orderbook. The default signal is a colored dot – green for changes on Bid, red for changes on Ask – which the user can customize.
The example shows the DOM levels 4410.75 and 4500.75 of the ES (S&P 500 Future). Resting limits are, in total, 40 lots and 400 lots on the price levels at this time.
The 40 lots consist of single-limit orders placed by different market participants: The Absolute Liquidity is 40 lots.The 400 lots consist of smaller single orders and one large order of 350 lots: The Relative Liquidity added on that price level is 350 lots, and the Absolute Liquidity is 400 lots.
