Hi Rob, How does your framework handle the inevitable loss of power or internet connection? Given the description of the hardware you use to run your system it sounds like the code is NOT hosted in some datacenter but rather executes in an environment such as your home where such a situation can and does occur.

Hi Robert, Great question. Yes I run my stuff 'at home'. There are a number of possible scenarios. In scenario one, I lose my internet connection, but then get it back. Some services, eg get account value and get price will fail gracefully treat what they get the same as a NaN. Orders that haven't been submitted will be delayed.

Given how slowly I trade, I can live with this. More seriously if an order is submitted and I miss a fill then I'll get a break between what I think my position is, and what the broker records say. Right now I lock the position to avoid duplicate trades until I've manually fixed the problem see http: I plan to rewrite this process to periodically check all fills received for the day and update the database; then automatically clear any position locks.

In an extreme situation if a process fails then the cron job will restart it the next day. The only thing that won't restart is the IB API gateway. In scenario two I lose power. The system has to be manually restarted. In the short term this is very similar to a loss of internet. In an extreme situation on holiday I might lose power for a couple of weeks before being able to restart. When I restart the system will backfill all the daily prices and the required trade will then happen.

Given the speed I trade at, I've tested the expected effect of this and I can live with it.

FC wrote this comment, which I accidentally deleted: I am super excited about your stuff and that you are UK based. Do you have an opinion about these: I don't have a problem with spread bets, but it's certainly true that if a future was available on the same terms same tick size I'd trade the future. Usually that isn't the case. So spread bets can be especially useful if you have a smaller account, but the wider spread means you'll need to trade more slowly.

Fortunately my account is large enough that I can just stick to futures. I discuss this problem in my book. Excellent - I've already ordered your book. Awaiting delivery from publisher. Hi Rob,I read really great reviews about your book and was adviced by a friend to take a look into it, however, I'm a novice to trading and investing, can you advice me what to read and learn before I start reading your book?

Thats a difficult question as it depends on what level you're at and which direction you want to go in. If you want to trade futures then reading Jack Schwagers books would be a good start. Hi Rob, Great book.

Please contact me if you would like to learn more about the services we provide. Hi Rob, first of all, thanks for writing the book, I found it really detailed and helpful. I've noticed a minor bug, in a summary just below Table 37, last item "Trailing stop loss when short" has a bug in math: Hi Rob, In your book you mention how hard it is to overcome the costs in spread betting.

For most EU citizens winnings on spread betting is tax free. Is that part of that calculation? No I didn't include tax in the calculation. But spread betting is around 10 times more expensive than say trading futures. Tax would need to be insanely high on futures to make spread betting more competitive. Hi Rob, Have you done any covered call writing?

It seems like a good fit for a systematic trading system. I haven't, but yes short volatility strategies like this are a good thing. Hi Rob, I came across your website while looking for someone who uses python for trading.

Thankfully I found you. I would like to thank you for the informations you share with us. I am totally interested in your book. However, I have a question about the content. Do you explain a strategy that you use to trade futures or strategies that can be employed? Because I never trade futures and I would like to start to trade by learning step by step from guidelines of your book if that is the case. What should I expect from your book?

Yes I explain some basic strategies to trade futures also ETF's and spread bets. But they assume some familiarity with futures already. Read something like https: Hi Rob, after reading your book, your blog here and your journal Elitetrader I decided to give it a try to program a system based on the framework you propose in your book.

My question is about the update rate you use during live trading? Your book emphasizes to not trade too much due to the involved costs. On the other hand, from your journal I get the impression that your system runs continuously as time stamps are all around the clock.

I was thinking myself to calculate account parameters once per day, preferably on a moment when all instruments are not trading account value relatively stable.

And recalculate instrument parameters once per hour only when they are trading. Should I sample instrument parameters more often? It depends on your holding period.

Currently I probably update too much hourly , given a holding period of a couple of weeks or more. I could easily update everything daily, and indeed in the next iteration of my code that is what I plan to do. As my trading rules will be slow do I expect similar holding periods.

A daily update rate will probably be fast enough. However, with several exchanges in multiple time zones involved does that lead to the question: Hi Rob, I think I noticed an error in your new Carry calculation worksheet https: I think you should delete the third element in the "And" function. Thanks a lot Interesting how Excel casts into logical type. Glad to help, thanks for all your advice in response to all my posts.

I have been paper-trading your "Chapter 15" system for a few days now. Could you please confirm the following with regard to your carry strategy: On November 4th, the closing price of Dec Eurodollar was Therefore the trading signal would be long.

So, I should be long the Jan contract, correct? What if the spread was significantly higher on the Jan contract. Would it be okay to go long the Dec contract? Would there be any reason to look at the Jan vs Feb contract, or should we always be looking at the closest two contracts in determining the forecast? Which contract you should trade I discuss more here: How to measure carry I discuss more in the appendices of my book.

Hi Rob, in your book you mention that is preferable to measure carry on equity futures by using the spot price.

Yet, in your python system, for EUROSTX, you use the further contract which is not held versus the nearer contract which, of necessity, must be held. A second question, if I may: Do you know why? But the fundseeder figures is lower because I have set a higher notional account value.

I spent 7 years working for AHL, a large systematic hedge fund earlier in my career I also spent about 18 months trading exotic rate options for an investment bank, Barclays Capital. My first job was to develop and manage a systematic mult-asset global macro trading strategy. Subsequently I managed a multi billion dollar portfolio of fixed income strategies futures, swaps, bonds and credit derivatives. See the 'about' page for more.

The system trades nearly 40 futures markets with an average holding period of several weeks, and has a mainly trend following character. I have written a book on systematic trading.
