Building Your cBot: A Beginner’s Guide


In the dynamic world of financial markets, spread betting offers a unique avenue for speculation on price movements across a wide range of financial instruments, including indices, forex, commodities, and shares, without the need to physically own the underlying asset. This method of trading is especially popular due to its tax efficiency and the leverage it offers, allowing traders to magnify their potential profits (and losses). Automated trading systems, known as cBots, play a crucial role in navigating the fast-paced and leveraged environment of spread betting. These tools enable traders to implement sophisticated strategies that can react in real time to market fluctuations, manage risks, and capture opportunities around the clock. This guide delves into the creation of a simple yet effective cBot using the cTrader platform, showcasing practical coding examples and providing insights into the nuanced world of spread betting automation.

cBots, the cornerstone of algorithmic trading within the cTrader ecosystem, are automated trading robots meticulously designed to execute trades based on predefined algorithms and without the need for manual intervention. This functionality is particularly advantageous in the realm of spread betting, where the swift execution of trades can significantly impact the profitability of strategies. The ability of cBots to operate 24/5, executing strategies with precision and discipline, offers traders a formidable tool against the rapid price movements and high leverage associated with spread betting. By automating trade execution, cBots help mitigate the emotional decision-making that can lead to costly mistakes, thus enhancing the overall efficiency and effectiveness of trading strategies in the volatile spread betting market.

How Do I Build a cBot?

To build a cBot, you’ll need:

  • cTrader Platform: Download and install cTrader from cTrader’s Official Website.
  • cAlgo: cTrader’s integrated development environment, cAlgo, is where you’ll write and test your cBot. It supports C#, a versatile programming language suitable for creating complex trading algorithms.
  • Basic Knowledge of C#: Familiarize yourself with C# programming. Online resources like Microsoft’s C# Documentation can be helpful.

Building a cBot for spread betting requires not only a grasp of programming and algorithmic trading principles but also an in-depth understanding of the intricacies of the spread betting market itself. To embark on this journey, you’ll start with the cTrader platform, renowned for its advanced charting, intuitive interface, and comprehensive support for algorithmic trading. Alongside cTrader, you’ll leverage cAlgo, its integrated development environment, to craft your cBot using C#, a language well-suited for developing complex trading algorithms. Essential to this process is a keen awareness of spread betting specifics, such as managing the variable spreads, accounting for overnight financing charges, and navigating the leverage and margin requirements unique to spread betting. These factors are crucial for creating strategies that can thrive in the spread betting environment.

Here’s an example of a simple moving average crossover cBot, which will execute trades when a fast moving average crosses over a slow moving average.

Writing code for a cBot that thrives in the spread betting market entails incorporating specific features tailored to the nuances of spread betting strategies. For instance, your cBot should include dynamic spread management techniques to adjust trading strategies in real-time based on the spread fluctuations. It’s also imperative to integrate a sophisticated risk management system, given the high-risk, high-reward nature of spread betting. This system could involve automated stop-loss orders, margin level monitoring, and the use of scalping strategies where applicable. The sample moving average crossover cBot provided is a starting point, which you can evolve by including these spread betting-specific features to enhance its effectiveness in this unique trading environment.

Sample cBot Code:

using cAlgo.API;
using cAlgo.API.Indicators;

namespace cAlgo.Robots
[Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
public class MovingAverageCrossoverBot : Robot
[Parameter("Fast MA Period", DefaultValue = 9)]
public int FastMAPeriod { get; set; }

[Parameter("Slow MA Period", DefaultValue = 21)]
public int SlowMAPeriod { get; set; }

private MovingAverage fastMA;
private MovingAverage slowMA;

protected override void OnStart()
fastMA = Indicators.MovingAverage(MarketSeries.Close, FastMAPeriod, MovingAverageType.Simple);
slowMA = Indicators.MovingAverage(MarketSeries.Close, SlowMAPeriod, MovingAverageType.Simple);

protected override void OnTick()
var currentFastMA = fastMA.Result.LastValue;
var currentSlowMA = slowMA.Result.LastValue;
var previousFastMA = fastMA.Result.Last(1);
var previousSlowMA = slowMA.Result.Last(1);

if (currentFastMA > currentSlowMA && previousFastMA <= previousSlowMA)
ExecuteMarketOrder(TradeType.Buy, SymbolName, Volume, "MA Crossover Buy");
else if (currentFastMA < currentSlowMA && previousFastMA >= previousSlowMA)
ExecuteMarketOrder(TradeType.Sell, SymbolName, Volume, "MA Crossover Sell");
