All of the option flow orders that are alerted on your dashboard are all "Ask side" orders meaning they are all buy orders.
FlowAlgo doesn't track orders that go off at the bid or the mid.
For equity blocks, remember this: For every buyer, there is a seller and for every seller there is a buyer. It doesn't necessarily matter for these. What does matter is the price action and behavior that follows after a transaction happens.
Large blocks tend to either fire off at, OR create support or resistance zones. If there are multiple blocks firing off for symbol XYZ at $10.00, if the price starts to drop well below $10.00 it can be seen as an indicator of bearishness. On the other hand, if it begins to move above $10.00 and continues, it can be an indicator of bullishness.
See the graphic below for another example.
Equity blocks and print data is best used as an indicator alongside technicals and other forms of data such as option order flow. They are only one part of the picture, and should not be used to form a trading decision on their own.
