Electronic trading emerged as the preeminent methodology of conducting enterprise over the 2000s in many of the world’s monetary markets.

Price/time Algorithm (or First-in-first-out)

The two most common algorithms used for order matching are generally recognized as price/time precedence (also called First In First Out or FIFO) and pro-rata, both of which have numerous strengths and weaknesses. One benefit of price/time priority is that it motivates market members to slender the unfold, which is the difference between the best quote on either side of the guide. A weak spot of price/time precedence is that it could be extra computationally demanding than pro-rata. To let the inventory trade deal with your trade orders, you’d need to be an authorized broker.
