Watching the order book is like watching a game of sumo wrestling..

You watch the 2 sides pushing and guess which will side will win..

1) You look at the size
You look at the size and see which side is bigger. Based on the size, you determine which side is harder to be pushed down or out. Back and forth.. push push push..

2) You look at the force
You look which side is stronger, which side has more force and momentum to push. It's so close, will the green has more force to push down the red although it's bigger?

3) Then you think.. could the match be fixed?
Could what you see now is fake? Could one wrestler intentionally step back to catch the other side off-guard?

Happy watching!
