Podcast-Cover300I answer three reader questions here, and stretch the boundaries of this podcast just a little bit.

Igor asks: “We know that the smaller the timeframe(TF), the more random the market is, and longer TFs are less random. If you want to risk X% of your capital than on shorter time frame (where stop loss is closer) you will trade bigger size than on the longer time frame where stop loss is further from entry. Do you think that those two statements negate each other? Since the longer timeframe is less random (we have bigger probability to make money) shouldn’t you trade bigger size and risk more?”

My answer to this question touches on quite a few important topics:

  • The importance of academic research
  • The nature of randomness
  • Longer timeframes are actually more random, from a quantitative perspective
  • Psychological and practical concerns can trump theoretical considerations of position sizing.
  • Above all, accept the risk you are trading with.

Jochen asks: “You talked a few times about remembering that charts are only a way of reflecting price action or buying/selling interest/history or in very generic terms what has happened in a market. Unfortunately I am anything but talented not even knowledgeable in terms of music, but I wondered whether you experimented with an acoustic representation of markets. I think you wrote about some type of alarm set-up in your 1min Nh-Nl trend day study, but did you ever go any further given you are both a professional musician and trader?”

In my answer, I ramble a bit (sorry, but that’s the nature of this episode!), and touch on my misguided and failed attempts at directly translating market action to music. I also talk a little bit about some of the benefits of a music background for market participants, relating mainly to focus and perhaps to some ability to manipulate abstract patterns in time. (I left music for business school and finance about ten years ago. Here is one of the last pieces of music I composed.)

Dave R asks: “How do I up my coffee game?”

My answer is first of all, clean your brewing equipment. I know that’s not an exciting answer (I would have dismissed it ten years ago), but it’s the truth. I don’t think vinegar and water works; you need something that cuts through the oil coffee leaves behind. Dishwashing detergent and a plastic brush works pretty well, but I’m a big fan of Cleancaf. It says espresso cleaner, but a small scoop of that dissolved in some hot water will eat coffee oil off of plastic, metal, and glass like you can’t even imagine, and works on any brewing equipment. Clean your machine so that hot water run through it tastes like nothing other than water. If you haven’t cleaned your machine in some time, this may be hard to do, but every cup of coffee tastes like the residual, stale, rancid oil baked into the machine. First, clean it well.

Next, I suggest starting with where you are, and moving up a notch:

  • Instant coffee? Then get ground coffee.
  • Big can of ground coffee in the freezer? Buy a good bag of freshly roastes (< 2 week old) beans and have them ground.
  • You guy ground coffee? Buy whole bean and grind at home.
  • You buy whole bean and grind at home? Consider roasting at home. (I didn’t get into this on the podcast, but I will if there is interest. Drop me an email if so!)

As for brewing equipment, I’ve tried every gadget and idea known to mankind. My favorites, out of literally 50 different ways I’ve tried to make coffee, are the Chemex brewers or a simple glass measuring cup and a fine sieve. (I also didn’t touch on espresso in this podcast, because that’s a different animal.) The idea is you want hot water to be in contact with ground coffee for 3-4 minutes, and then want some way to get the water separated from the coffee. It’s not as complicated as many people would like you to believe, but details matter.

Thanks for the questions, and keep ’em coming!
