Testing our high frequency trading trading tester has always been a challenge. The amount of trading, and the complexity of that trading, have been increasing rapidly. This has led us to deploy more machinery to ensure we are performing as we expect. The three phases of our testing life cycle were as follows. Our simulators started off trading tester. The market data simulator produced random but meaningful market data shout out to the prroject. It was tedious, but this method allowed us trading tester tradeshares a day.
As our trading increased, understanding how the algorithm trading tester operating over time became more important, and visualization is a key answer to looking at large amounts of data. As the algorithmic logic makes trading decisions, it logs name-value pairs of all the data it trading tester using to make a decision. We then parsed these name-value pairs into trading tester table format with the name mapped in columns, and each time-stamp in rows.
We then created numerous graphs, up to 20 per algorithm. Our research team then looked in detail at these graphs to understand whether the algorithm was behaving as expected. This was very helpful as we could now acertain what our system was doing and discuss the results easily as a group. We rely on graphs to discuss complex corner cases to help us trading tester complex market structure.
The issue, however, is that trading tester understand the graphs requires someone who is well-versed trading tester what each particular algorithm is trying to do. This helped us reach 5 million shares a day, but it began having problems identifying when corner cases had been encountered, and analyzing enough data to know we were always doing the right thing. Graphs were good but we needed automation. Our EmitTest framework evolved out of this need. Trading tester central idea around the EmitTest framework is that a system is comprised of various interacting objects that change as time trading tester.
These are linked to each other by references in the JVM shout out to Java: Events take place that cause these objects to change, sometime resulting in changes to trading tester objects. The EmitTest trading tester looks to capture and analyze this object-state-through-time graph. IEmittable are objects that can spit out their state at any time. When they do so, they create a unique emit row emitID being the primary key. What this gives us in the emit data is all the objects in the system — whhat trading tester there state was at particular known times in the past, and what the state of their linked objects was trading tester that time.
This emit data can now be loaded into a set of Java objects called Emissions. Emissions, which are wrappers around a map, allow querying on the value of a particular variable for that Emission.
Emissions also allow navigation through time Emissions. This creates an entire object graph of each object in our system, its state through time, and its link to every other object and its state through time.
These EmitTests can then either pass or fail, and we log the fails and pass-counts. This allows us to then confirm that a production day has no issues. This also trading tester with our continuous build server shout out to Bamboo. We make extensive use of annotations and ensure the tests can be written trading tester part of the strategy itself.
In addition, Emissions and EmitTests can be derived from, making this a trading tester way trading tester make the nodes of the test graph the Emissions become stronger through time, to allow building blocks to be available to further test writers. This, in combination with Hadoop and Amazon EC2 shout out to themwill allow us to run simulations of our clients trading back through time and allow us to test far more corner cases more quickly.
Testing of algorithmic trading strategies is a complex task, one that has taken us several years to crack. The EmitTest framework has been running now for some time and has helped identify numerous trading tester with our trading tester algorithms, allowing us to become more confident when rolling out new Strategies. An algorithmic trading saga trading tester Testing our high frequency trading platform has always been a challenge.
