Depth of Market, page-4

i disagree,

Spark API you can get access to depth data and if there are enough new orders pre market on the buy side and the price is gapping up on open, it will not only gap up on open, but it will keep on going, making it a safe trade to enter and to put a stop on when in profit.

The preceding price action over the last weeks and months plays into this as well

the down side is, you are going to be watching this each morning for a year or two or even longer to get your golden opportunity to trade

but when you think about it, that is not long to become an instant millionaire
