Recently, I thought of something. For ordinary investors like us, there are almost no advantages in trading speed and performance.

Why is that? Because order placement speed depends not only on how fast the program runs but also involves factors like network latency and account level. Many exchanges intentionally set delays for regular accounts, granting VIP or special-level accounts priority in order matching.

As a result, certain traders can exploit this speed difference to arbitrage — we usually call this delay arbitrage. Simply put, it’s about leveraging the execution speed advantage brought by account levels to execute trades ahead of market movements and profit from them. For most retail investors, this game rule itself is not very fair.
