Below is a chart with signals based on the EMA signal just like in our first case. But this time I have chosen a different region and more data. In this case I tried to let the system make a profit in a very short amount of time by leveraging the high volatility. Everything shown on the chart is what was used to generate the trading signals and compute the ROI. In practice, we have to run our algorithm on days, weeks, months or even years worth of data to verify its success rate.

Unfortunately very few of these strategies proved to be successful in our tests. Deep data Using raw market data e. Unless your algorithm is pretty sophisticated and well-designed — if so re-check everything because you may have a bug or unaccounted for scenario after all. After a long time and countless attempts I did manage to come up with a few profitable trading algorithms.

These were achieved by utilizing some default indicators which I had to adjust in several ways prior to applying. Notice how far apart the buy and sell signals are compared to our previous examples. Here they are many hours or even several days apart, while previously it was just minutes or a few hours. Before I sell my kidney and go all-in, I need to make sure it will really work. But what if we can use A. At some point, if not already, A. If you are an A. Hybrid modelling Until some weeks ago I was using a manually designed strategy which used our predictions to generate trading signals.

What comes to mind is that these strategies are short-term, meaning they use whatever its predicted to make a decision in the moment. Since our predictions are usually no more than 3 to 15 minutes into the future, they will need to generate large enough margins to pay off the trading fees and thus generate a positive ROI. This is triggered by the acquisition which is a corporate event. If you are planning to invest based on the pricing inefficiencies that may happen during a corporate event before or after , then you are using an event-driven strategy.

Bankruptcy, acquisition, merger, spin-offs etc could be the event that drives such kind of an investment strategy. These strategies can be market neutral and used by hedge fund and proprietary traders widely.

Statistical Arbitrage When an arbitrage opportunity arises because of misquoting in prices, it can be very advantageous to algorithmic trading strategy. Although such opportunities exist for a very short duration as the prices in the market get adjusted quickly. Market making provides liquidity to securities which are not frequently traded on the stock exchange. The market maker can enhance the demand-supply equation of securities. How to Validate Your Edge Back-testing an algo strategy involves simulating the performance of a trading strategy using historical data.

This means you test a strategy, using price action that has already occurred. This form of validation, gives you an opportunity to estimate the effectiveness of your edge. Back-testing your algo is a starting point. It should not be used as final validation, but works well to determine if your edge is worth pursuing. One caveat to consider with back-testing, and then analyzing your results, is the trap of optimization. This is a vicious trap of perfection. Once you have preliminary validation, move onto simulated trading.

Simulated trading, tracks your algo strategy against live market data. You get results and feedback without the benefit of knowing the outcome of price action. In essence, you cannot choose the perfect day to validate your edge.

This process is obviously slower, because you can only test one day at a time. The benefit is you cannot make tweaks in hindsight. You let your algo strategy run the entire day and then review the data for any possible changes. Live trading to validate your algo strategy is by far the most effective method for a true validation. You get feedback that shows actual executions, and how your trading program performed within the two critical market conditions of, liquidity and volatility.

Algorithmic Testing applied to Liquidity and Volatility While valuable, back-testing and simulated trading provide feedback for trades that never occur. This can give false hope. Because back-testing and simulated trading never add or removes shares from a market, you will truly never know performance until you attempt trades that interact with available shares in the market.

Liquidity identifies the ease with which you can execute a trade, because there are shares quoted at the bid or ask, and your algo, and a transaction took place. Slippage means you anticipate not receiving the perfect fill price that you received while back-testing or simulated trading. Large orders, without liquidity, can be a slippage disaster. Volatility represents, how fast and how far, a security moves, within a designated period of time.

In trading lingo, many who use technical analysis determine volatility, by using the Average True Range indicator. This means if you are trading AMZN, the swings are much wider and share size must match your risk tolerance. The same applies to futures contracts. Liquidity and volatility are key elements to consider when validating your algo. Algorithmic Trading Strategies There are literally thousands of potential algorithmic trading strategies, here are few of the most common to jump start your journey: Your edge is determined by identifying an obvious direction to order flow.

This edge could be over months, or over minutes. The key to success with this strategy is defining the time frame to operate.
