Master Course on Network Optimization: Efficient Handling of Stagnation Problems in US Stock Trading??? Solution//Global IPLC service provider of Shigeng Communication

一、In the world of US stock trading, speed is the lifeline. A negligible lag, a delayed quote, or an order that was not executed on time can all mean the loss of huge profits or the loss of control over risks. For intraday traders, scalpers, or algorithmic traders, network latency is not only a nuisance, but also a deadly enemy.

This article will delve into the root causes of stuttering in US stock trading and provide an efficient processing and optimization framework from hardware to software, from network to strategy, to help you create a stable and high-speed trading environment.

1. Root cause of the problem: Why is your transaction lagging?

To solve the problem, the first step is to accurately locate the problem. Trading lag usually originates from the following four levels:

Local hardware and system resource bottlenecks: CPU overload, insufficient memory, slow disk read and write speeds (especially when using mechanical hard drives), and background programs consuming a large amount of resources.

Improper configuration of trading software and platform: poor optimization of the software itself, excessive loading of indicators and data in charts, frequent alarm settings, and excessive historical data.

Network connection quality and path issues: These are the most common and core reasons. including:

High latency: The time required for data packets to travel from your computer to the exchange server and then back is too long.

Jitter: The instability of latency leads to unpredictable data arrival times, which is particularly fatal for algorithmic trading.

Packet Loss: Some data is lost during transmission and needs to be retransmitted, causing information interruption.

Poor routing path: Your data did not take the optimal path and may have taken a long detour at a certain network node.

Data source and broker server issues: There is a delay in the Market Data Feed you receive, or your broker's order execution server is overloaded.

2. Efficient Processing Framework: Four Layer Optimization Strategy

We will adopt a systematic approach that progresses layer by layer from the inside out to solve the stuttering problem.

First layer: Local hardware and system optimization - building a sturdy fortress

Hardware upgrade (non compromise item):

CPU: Choose a processor with a high frequency (GHz), as for high-frequency trading, the number of cores is not the top priority.

Memory (RAM): 16GB is the starting size, 32GB or above is preferred. Ensure that the trading platform and data flow have sufficient memory to operate.

Storage (SSD): NVMe SSD must be used. The extremely fast read and write speed ensures fast loading of operating systems, trading software, and historical data.

Network equipment: Use gigabit or above network cards and consider using high-quality enterprise or gaming grade routers to better handle network traffic.

System purification:

Dedicated for private use: Ideally, trading computers should not be used for playing games, downloading large files, or browsing unrelated web pages.

Close irrelevant processes: Disable all unnecessary startup items and background applications (such as cloud disk synchronization, automatic updates, real-time scanning of antivirus software, etc.) in the task manager. During trading hours, it may be considered to temporarily disable antivirus software (one needs to weigh their own security risks).

System power settings: Adjust to "High Performance" mode to prevent CPU frequency reduction.

Keep up-to-date: Ensure that the operating system and trading software are kept up-to-date for performance optimization and vulnerability fixes.

Second layer: Simplification and configuration of trading software - reducing software burden

Simplified workspace:

Reduce the total number of open charts.

The fewer technical indicators loaded on each chart, the better. Each metric is an additional burden on the CPU.

Clean up unnecessary drawing tools and alerts.

Data management:

Regularly clean or archive historical data. Long historical K-line data can consume a significant amount of memory and loading time.

Choose the necessary data flow based on your trading style. For example, if you do not trade options, you can close the option chain data.

Third layer: Network connection optimization - laying the information highway

This is the key to victory and the core of the 'master class'.

Abandon Wi Fi and use wired connection: Ethernet cable (Cat6 or above) must be used to directly connect to the router. Wi Fi is unstable, susceptible to interference, and has significantly higher latency and packet loss rates than wired connections.

Choose a low latency internet service provider (ISP): Study which ISP in your area provides the fastest and most stable network routing to your broker's data center. Sometimes small local ISPs actually have better routing.

Conclusion

Dealing with trading lags in the US stock market is a system engineering that requires traders to be both financial experts and half IT engineers. By following a four layer optimization strategy from the inside out: strengthening local hardware ->streamlining trading software ->optimizing network paths ->selecting high-quality data sources and brokers, you can systematically eliminate latency points and build a stable and high-speed trading environment.
