I went on a long walk yesterday. You could argue that it was pointless. I was going nowhere in particular, and ended up where I started. However, on the way I got a bit of exercise, and it was a nice break from being at home. Another good reason is that I often seem to…

Using Python to explore FX market microstructure
by Saeed Amen •
I am sure like most readers, I’ve lost count of the number of weeks since things were “normal”. When will things get back normal? Maybe weeks or more likely months? I suppose that using a Python function random.random(), might be the best approach here! However, in the meantime, I’ve been trying to work hard at…

How to do TCA with tcapy in Python
by Saeed Amen •
Over the past few years, I’ve been working on tcapy, a transaction cost analysis library in Python, which I’ve recently open sourced. As a result I’ve been thinking about TCA for a long time. Why is it important to do transaction cost analysis on your trades? Ultimately doing TCA can save you money on your…

Speeding up tick data calculations in Python
by Saeed Amen •
Time, time, time. At the current moment, we likely have a bit more time than usual. Despite this, it’s unlikely any of us actively want to wait longer for code to execute! Last week, I wrote about libraries for working with large datasets, like Dask and Vaex, or using databases like kdb+/q. This week, I’ll…

Libraries for large datasets in Python
by Saeed Amen •
People say the best way to learn something is to teach it. It’s obviously a bit of cliche, but I have to admit it’s one of things which really does ring true. When I’m researching the markets or coding something, I’m generally pretty focused at the task at hand. I’ll learn what I need to…

Learn Python to automate regular market tasks

Over the past few weeks our routines have changed somewhat. I’ve made fresh pasta, which resembled something quite unlike any other pasta I’ve tasted. Entirely coincidentally, I’ve discovered why I should not make fresh pasta, and there’s a reason why folks buy ready made pasta. Aside from delving into the world of pseudo-pasta creation, like…

Writing a story with alt data
by Saeed Amen •
I seem to spend most of my time writing. For over a year Alexander Denev and I have been coauthoring The Book of Alternative Data. I’ve also written a few papers on alternative data and FX recently. Aside from that, I’m still writing, although usually in Python and I’ve also recently started to learn kdb+/q.…

Paying the yeast amount for TCA
by Saeed Amen •
Whether the coronavirus pandemic is a Black Swan or a White Swan event, has provoked a lot of discussion over recent weeks. Nassim Taleb noted that it was a White Swan event (see his recent Bloomberg interview), because we had some warning that it could spread, earlier in the year after it had appeared in…

The importance of data visualisation
by Saeed Amen •
In finance, we spend so much time doing analysis and working with data. What’s the most important part of the process? Clearly, sharing your findings. If you are unable to communicate what you’ve done, and your audience can’t understand it, the value of your research is reduced. One way to share your research is through…

How to speed up Python and TCA
by Saeed Amen •
Somewhat abusing a quotation by Dickens, coding is the best of times and also the worst of times. The worst of times are those hours spent debugging, what appears to be some innocuous code, that throws an exception for some totally inexplicable reason. When you find the problem it is usually something which was incredibly…
