What is Software Trading, and Why is it Important?
Published: 2024-04-24 12:53:01

Software trading refers to the use of specialized computer programs and algorithms to automate and execute trading decisions in financial markets. Instead of a human broker making trade decisions, software trading relies on complex code and mathematical models to analyze market data and place trades accordingly.

## The Rise of Algorithmic and Automated Trading
In the past decade, custom trading platform development has become increasingly widespread due to:

- Advances in technology that allow for faster and more complex analysis of market data
- Ability to execute orders rapidly to take advantage of small pricing inefficiencies

Demand for lower trading costs and better execution quality from institutional investors
According to industry estimates, over [75% of all trades in US](https://www.quantifiedstrategies.com/what-percentage-of-trading-is-algorithmic/) equity markets today originate from automated trading systems. These systems perform functions often referred to as algorithmic or automated trading.
Additionally, increased computing power at lower costs has made complex automated trading systems more accessible to retail traders and smaller funds. Open-source software frameworks like Python and R allow quicker development of trading algorithms. Cloud computing has enabled easier deployment and distribution of trading models without expensive hardware investments.
Regulators have also adopted more electronic trading-friendly policies, which facilitate the proliferation of automated traders. Initiatives like the SEC's Market Information Data Analytics System (MIDAS) focus on monitoring automated trading activities much more closely to prevent market manipulation and flash crashes.
Overall, the supportive technological and regulatory environment, coupled with increasing investor trust, has provided tailwinds for automated software trading to continue its rapid growth trajectory over the coming years across consumer and institutional categories. Estimates suggest that most of the daily [volume on US equity exchanges](https://fastercapital.com/content/How-Stock-Exchanges-Affect-Average-Daily-Trading-Volume.html) will originate from machines rather than humans by 2025.

## Key Benefits of Software Trading Models
There are several major advantages software trading tools offer compared to traditional human-based trade execution:

### Speed and Complexity
Computerized models can process vast amounts of market data, identify opportunities and place corresponding orders in fractions of a second. This allows them to take advantage of even the smallest pricing anomalies. Humans simply lack this speed and data processing power.

Advanced machine learning algorithms like neural networks can further enhance trade signal generation accuracy by uncovering complex hidden predictive patterns in market behavior that are difficult for traditional quantitative models to understand. This provides a key edge in remaining profitable in competitive, low-signal environments.

### Emotionless Decisions
Automated trading systems adhere strictly to their underlying math models and rules. They do not experience fear, greed or other emotions that can negatively influence human trading judgment. This helps minimize errors and realize incremental gains that accumulate over time.

Emotional distraction and bias have measurable detrimental impacts on trader performance, often exacerbating losses during periods of high volatility. Algorithmic models maintain consistent, rational discipline in their analytics and trade execution across diverse market conditions, avoiding this downside.

### Lower Costs
After the initial development, the [marginal cost of running algorithmic trading systems](https://utradealgos.com/blog/ten-reasons-every-trader-should-get-their-hands-dirty-with-algorithms/) is very low. This allows investors to minimize transaction fees and optimize their overall costs.

In addition, software tools clearly understand probabilistic outcomes and optimize position sizing accordingly to manage risk on a trade-by-trade basis. Humans struggle to gauge these odds precisely, especially during volatile, highly fluid environments. Minimizing fat tail risks translates into substantial cost savings over the long term.

### Diversity and Scale
Automated tools allow for the implementation of a wide variety of strategies spanning multiple asset types/markets simultaneously. This enhances portfolio diversification while keeping costs low.

The scalability of computerized models makes opening and closing a large number of small positions across diverse instruments feasible based on statistically significant signals without materially increasing operational burdens. This expanded trading breadth magnifies the monetization of short-term alpha opportunities.

### 24/7 Markets Monitoring
Software tools can monitor and trade on markets around the clock. Humans cannot match this constant level of analysis and surveillance. This ensures trading opportunities are not missed even outside regular hours.

Today, meaningful information relevant to price discovery across equities, commodities, and foreign exchange is distributed overnight and in regular trading sessions. Algo systems ingesting inputs continuously are better positioned to capitalize on resulting price swings in a timely manner. Their computing infrastructure remains unaffected by fatigue or distractions.

## Types of Software Trading Tools
There are two broad categories of automated and algorithmic trading solutions available today:

### 1. Off-the-shelf Platforms

These are ready-made trading platforms offered by various specialized financial technology vendors. They allow users to implement pre-made trading strategies or build custom models through a visual, “drag-and-drop” interface without coding skills. These tools are user-friendly and can be up and running very quickly. However, they offer less flexibility compared to custom-coded algorithms. Examples include TradeStation, QuantConnect and Quantopian.

### 2. Proprietary/Custom Systems

For hedge funds and institutional trading firms with specialized trading requirements, developing proprietary trading systems with unique math models and logic makes sense. These custom platforms are coded from scratch by expert developers, either in-house or outsourced. While requiring significant upfront investment, proprietary systems allow maximum control, customization potential and uniqueness.

## Why Customization is Key for Effective Software Trading
The main advantage of software trading is the ability to codify and automate a rules-based approach tailored to one’s specific trading philosophy, market niche, parameter tuning and risk management preferences.

Here’s why customization capability is so important:

### Optimizing for Particular Assets/Strategies

Customization allows automated trading tools to focus exclusively on particular assets like equity indexes, FX crosses, or commodity futures and build suitable models, respectively. Pre-built platforms have a more generic focus.

### Incorporating Proprietary Data

Custom systems can integrate external data like credit card transactions, supply chain reports or weather forecasts. This provides additional alpha-generating insights compared to just market price/volume data.

### Responding Rapidly to Changes

Financial markets evolve quickly. Custom platforms allow models to be modified rapidly as market dynamics shift, whereas generic platforms move slower.

### Complex Math and AI Integration

Specialized trading strategies like statistical arbitrage, neural networks and natural language processing rely on complex math. Custom coding allows for the seamless integration of these models.

### Strict Risk Management

Parametrizing risk levers like position sizing, stop losses and volatility scaling is easier on proprietary platforms for managing overall portfolio risk.

In summary, the level of configuration and customization supported is a key differentiator between software trading tools. With the right approach, automated trading can enhance portfolio returns while minimizing risks. But no “one-size-fits-all” solution exists. The flexibility to tailor systems to one’s trading style provides a significant edge.
