Correlation not causation. Ok, we’ve heard that thousands of time before. The difficulty is that we cannot simply ignore correlation if we are trading financial markets. The relationships between different assets and other data is often crucial to forecasting the market. If we were forced to ignore it, you’d end up ignoring so much data…

Criteria to judge datasets

There are McDonalds everywhere. It’s probably the most ubiquitous fast food joint. If you want a burger, and want it quickly, it not a bad choice (double negative intended). Is it the best choice for a burger? My uncontroversial response would be, no. I doubt many readers would find an issue with my answer. There…

Tapes, CDs and trading
by Saeed Amen •
I remember cassette tapes. The clunking sound when you closed your Walkman, the art of fast forwarding just enough to catch the next track, but not too far to miss half of it. I remember being in awe when we got our first CD player at home, and hearing it for the first time. It…

Different ways financial data is used

The weather is one of those universal neutral conversation starters, at least it in the United Kingdom (and well, let’s just steer clear of that conversation topic called Brexit for a few minutes). Hot weather isn’t always desirable. I was recently in Geneva, and had been expecting very cold days, bracing myself for a torrent…

Using images in trading

There are some things computers can’t really do. They can’t enjoy a good burger. They don’t seem to understand the importance of knafa. Ok, perhaps these aren’t really that important. However, people are still pretty good at doing many things, that computers haven’t been able to do well, at least until recently. Any toddler can…

The music of the markets
by Saeed Amen •
Feet tap. Hands clap. Heads shake. Music affects us. It moves us. By contrast, noise annoys us. Car horns beeping. Trains braking. Rain falling. It’s all sound. Yet it is obvious to discern the difference between music and noise. Music has intent, it has rhythm, it has pitch. Noise is an unwanted byproduct of our…

First steps of building quant
by Saeed Amen •
If I want to get something done, I find procrastination is the optimal strategy. Well, I suppose optimality is dependant on the time horizon. In the short term, it is nearly always optimal. In the long term, it is less clear whether procrastination will always be an optimal strategy. Eventually though you’ll have to do…

New Year 2020 quant resolutions
by Saeed Amen •
January. Cold. Rain. There’s little to be joyful about this month. However, amidst the gloom, there is that shard of light which crosses over into the future. In particular, the New Year gives you an opportunity to start again, that imaginary line of sand, separating you from the past 12 months. It’s that time when…

Hundreds of quant papers from #QuantLinkADay in 2019
by Saeed Amen •
I probably tweet too much. Some tweets are on burgers (well, they are pretty important I suppose). Other tweets will constitute puns, which I find mildly amusing, but most term as “dad jokes”. Among all of these tweets, there is also stuff about Python and quant more generally. In particular, I tweet out #QuantLinkADay, which…

Putting quant into your market analysis
by Saeed Amen •
It’s impossible to know everything. Furthermore, as the cliche goes, the more you learn, the more painfully apparent it is, that there even more out there left to learn. I like burgers, but despite years of eating burgers, I’m not sure I can consider myself an expert. After all, I’ve only sampled a very small…
