A method, system and computer program to monitor securities market activity. Level 1 and/or level 2 data is analyzed to track the activity of market makers and to derive indicators of momentary upward or downward price pressure. As items of information relating to level 2 data are received, processing block (218) will pass these items to the level 2 data subprocess (238). In processing block (240) the level 2 data subprocess (238) will determine if each incoming level 2 data value corresponds to an item contained within the user's database, including securities contained within the watch list and alerts. If not, the level 2 data item will be discarded in processing block (242). Otherwise, the level 2 data item will be passed to processing block (244). Any changes to the user's database since loading of the information contained within the user's database in processing block (212) will be considered by processing block (240). Those updates will also be considered for each of the processing blocks (244) through (256). |
