The challenge for systems traders is having the know-how to create an algorithmic strategy, coupled with the knowledge to analyze whether or not the strategy is robust. Historical Data Requirements Systems traders will want to simulate the real-world market as closely as possible. For example, trading costs such as commissions, exchange spreads, and slippage can chew away at returns. Though the effect on an individual trade may be small, these small pieces of data can throw off the backtest results if they are ignored.
A couple of different types of market data are used in systems backtesting that you need to be aware of. Candlestick and order book data are both used in backtests, but order book data is usually more reliable. First, you have no idea which prices have been traded for which volume.
Traders typically call on candlestick data because it is the easiest to acquire. Order Book Data A sample of Bybit's order book An order book is one of the best data sources that resolve many of the challenges of candlestick data. Order book snapshots allow developers to simulate bid-ask spread , slippage, and liquidity when testing a strategy. The challenge with order book snapshots is that the data may be difficult to come by.
There is a tremendous amount of data within order book snapshots, and exchanges choose not to hold the data, as it would be expensive to store. Therefore, a developer needs to collect and store data from the exchange itself or access the order book snapshots through a third-party service.
Automated Backtesting Algorithmic trading aka automated trading or black-box trading refers to traders who use a computer program to define a set of instructions to execute a trade. Thus, the backtesting of strategies can also be automated. By implementing automation, we can also automate the results to arrive at helpful statistics, helping us determine if the strategy will be effective. Deciding on a Programming Language Before choosing a platform to backtest a strategy, make sure your preferred markets are supported.
Also, choose which programming language you would like to use. Some third-party services and API extensions you can subscribe to provide the back-end data and a front-end platform that is a little easier to backtest.
Altrady, Holderlab, and Shrimpy are a few examples. The backtest needs to spit out a profit and loss analysis by trade and day. That way, you can create an equity curve that shows what the account balance would have been if it were traded live. The equity curve is simply a time series chart showing the value of the account balance each day or after each trade. Success Ratio and Sharpe Ratio The success ratio is the win ratio of the strategy.
By itself, however, the win ratio means nothing and is misleading. Another metric used to determine how robust a strategy maybe is the Sharpe ratio, which illustrates what the returns are like on a risk-adjusted basis. This allows the trader to compare two completely different strategies based on the risk taken to yield those returns.
Simulated Backtesting Simulated backtesting simply means running a test over historical data that simulates the market environment. An automated backtest is conducted using programming and code to speed through the process. Testing several months of data takes just a few minutes, depending on the speed of the computer. By contrast, a manual backtest simulates the historical market as a trader selects a predetermined point in time, then walks forward the market to determine if a buy or sell signal is generated.
The time involved in a manual simulation is much longer, which is prone to several possible errors. To determine which is best for you, consider the following questions: Do you know how to program and code? Are you willing to pay for a third-party service to backtest?
This provides you with more flexibility and control over what you can do and any tweaks needed to improve your strategy. Generally, these services allow you to create your strategy on their platform and then run the strategy against the historical data. There is some convenience they provide to you, but you lose control over the reliability and quality of the data. Of course, these services will come with a cost as well. This will be the most time-consuming method, but it does allow you to see how the strategy performs and reconstructing trades based on your likings.
Trading costs such as spread and slippage tend to be overlooked with this method, so make sure you include an estimate for them. The success ratio, average winning trade, average losing trade, and Sharpe ratio are important to understanding the backtest and must be considered. In addition, consider how long of a backtest period was chosen. The longer the backtest period, the more likely the results will include multiple market conditions. Shorter backtest periods will less likely be a good reflection of robust strategies.
Finally, what was the maximum drawdown? The maximum drawdown is the amount of the account lost during an aggressive losing streak. Drawdowns will always occur, and if the drawdown is too large, you may not have enough capital to support the strategy. This is because future drawdowns in a real environment tend to be bigger than those simulated during backtests. The solution? You can backtest your strategies on historical data to confirm if they work or not. If they work on different timescales, you now have enough proof to risk hard-earned money on the trade.
Optimising your strategy As a trader, you tend to change your strategies with experience. The problem with this kind of optimisation is that it comes at the cost of real money.

You can run every new iteration of your strategy through backtesting programs and optimise your market moves. And backtesting is the perfect way to put the wind in your sails.
After testing your strategies multiple times, you can be sure of their effectiveness. This will give you the confidence to dip your toes into crypto waters. How to get started?

A trading method can be using indicators, price action, or fundamentals to take a position in the market. Make sure to practice the method on your preferred choice of an asset to ensure it is working. Some traders use a combination of technical and fundamental analysis to better gauge the market sentiments while others simply focus on one.
Determine your entry and exit rules. You need to know when to enter and exit the market based on your trading strategy. Back-test and forward-test your method. To determine the accuracy of your trading system and trading rules, you need to backtest it on historical prices to see how it would have fared.
If it performed well, you forward-test by paper-trading on a live market basis to see if it can still be applied to current market conditions. Remember that taking your time to master a given strategy is better than jumping on the bandwagon ill-prepared and losing your investment capital. Which crypto to make strategy? As stated before, volatility varies among different coins, and studying them subjectively will help you from avoiding losses. This might be suitable with a high-risk tolerance but swings such as this are sufficient enough to go get you stopped out of a trade.
A crypto-specific trading strategy might be best if you are trading different coins at a go. Since the price of ETH is more stable than PERP, it will be okay to hold it for a few days without worrying about getting stopped out due to daily price fluctuations. Cryptocurrency strategy for beginners As a beginner, you must find a strategy that suits your personality and circumstances.
Having said that, here are different strategies used by crypto traders: Scalping Scalping has become a popular strategy in the crypto market. This strategy takes advantage of the little price fluctuation at frequent intervals. The high volatility in the crypto market has made scalping a suitable strategy since there are many opportunities for quick profits. Scalping aims to build on small profits over a long time.
However, developing a scalping trading strategy is very difficult and requires lots of volatility. Scalpers open multiple positions in smaller time frames such as 1 minute, 5 minutes, and 15 minutes, and trades are opened and closed frequently with the use of tight stops.
They may use leverage to maximize profits. Scalping is not suitable for all traders since it carries a high risk and can have a significant effect on your emotions. Day trading Day trading involves entering and exiting positions within a single day. Your aim as a day trader is to capitalize on the intraday price movement of assets. Traders in this category normally use a higher timeframe like the 15 minutes, 30 minutes, and hourly timeframes for entry and exits. Most of the day trading strategies rely on technical analysis.
Swing trading As a swing trader, your main aim is to capitalize on price swings spanning days and even up to a week or more. It is a medium-term trading strategy since it is a bit of a day trading and position trading strategy. As a result, it gives you more time to consider your trading decisions which means less room for error while eliminating emotional trading. A swing trading strategy is more suitable for beginners because of the lower risk associated with it.
Position trading or trend following Position trading gives you the liberty of holding your trades for a longer period. Short-term price swings are not considered in this strategy, as your focus is more on the longer-term trend. Fundamental analysis is the major decision-making factor here, but some traders can use both fundamental and technical analysis to fine-tune their entry.
Trades are helpful for weeks, months, and in some cases years. Most profitable crypto trading strategy There is no one-size-cut-all trading strategy but some trading strategies have a higher performance than others. How well you follow trading strategies is also a big factor in how profitable it can be. Also, how you manage risks can have a significant impact on your profit factor.
Traders who use tight stops may be subject to a series of losses compared to those that use wide stops read here for the pros and cons of stop loss. Although wide stops can save you from incessant knockouts from trades, they can also leave you with large losses enough to blow your account. So, you need a well-calculated risk management method. By and large, medium to long-term trading seems to be more profitable than short-term trading.
Short-term trading always puts the trader on the edge, which might give room for errors. However, because cryptocurrencies are a relatively new asset class, the data is limited for proper backtesting, in our opinion. That said, Bitcoin has been a good vehicle for trading because of the volatility and its powerful trends either up or down, must up since its inception, though. Below is a chart showing the ups and down of Bitcoin: Cryptocurrecy trading strategy Bitcoin price chart Keep in mind that the chart above has a logarithmic scale — the only correct visual display of time series over many years or assets with huge volatility what is log scale chart?
The same trading strategies that work on stocks are much less likely to work on Bitcoin or any other cryptocurrency. This is to be expected. So far, cryptocurrencies have worked well as trend following strategies and less well on mean reversion strategies. Is this likely to continue? We suspect cryptocurrencies will gradually lose some of their trend-following abilities as it continues to become more and more mainstream.
The trading strategy reads like this in plain English: Buy at the close if the close breaks above the day simple moving average. Sell at the close if the close breaks below the day simple moving average. This is as simple as it gets. End date — select the end date of the test. Rebalancing options — allows to choose a strategy for rebalancing cryptocurrencies. Rebalancing strategies include a choice between threshold and periodic rebalancing.
