I know why people use buy and sell walls, but why do they do both so close together?
Right now on poloniex. Eth-USDT has a sell wall of 286.28 and a buy wall of 284.44. It's not even a two dollar difference. Why do they do this? It's this way on about 10 coins that i've looked at.
Actually this thing depends upon the many factors .
The first factor is the value of the coin , if value is much down then surely thier will be big difference between buy and sell wall .
Second factor is to the future , if discussion is of the future then people will buy at buy and sell wall , because they know why they are buying .
And thir factor is non understanding , that I seen many times , Few people who are newbie bought the coins at the high price and making the price wall of the buy order high then the sell order .
So all things are depends upon the demand that is going on at the current time in the market about the particular coin .
