- Ability to execute a big order at the best price (large market depth)
- Minimal spreads
- Ability to trade large volumes without the risk of shifting the market
- Best prices, minimal spreads, and the biggest volumes all in one place
There are also limits to the advantages you mentioned right? Imagine there comes a huge whale to your exchange and buys a billion dollars worth of Bitcoin, that's going to affect the market I'd expect?
Of course, this will affect the market. But if the rest of the stock exchange this action could collapse, then liqunet will purchase the necessary volume on several exchanges, which does not warp the skewed one big deal.
That requires a very fast trading engine for your setup to make that all work in real time if huge trades need to be executed!
At the moment, at the most simple equipment we have 18000-20000 transactions per second, if necessary, the core easily scales into several servers and the productivity can be increased by an order of magnitude.
I have no clue how many transactions these large exchanges right now process per second, but 18000-20000 sounds about ok I guess.
