So looks like some(most?) instruments (like Dax40) have different Local Class property for monthly and weekly that allows to filter out weekly contracts without providing LocalName. Then the problem is only to find all EUREX contracts (in addition to M1MS) which have the same local class for weekly and monthly\quarterly expirations. I'm pretty sure that my system would already be screaming about missing EOD prices if there were problems with any other contracts, I'm only trading these from EUREX: ESTX50, V2TX, BTP, OAT, GBM, GBL, SMI, BTS, FBON, M1MS, DJSD, SX3P, SXEP, SXTP, SXDP, SX8P, SXPP, SXAP, SXRP, SX7E, DAX, GBX
Always check with every contract what type of naming system it uses for local name. I had to change code a few months ago just for FDXS monthly contract, so that it now uses "Symbol + Third friday of expiration month + M".
So apparently I got lucky: I don't use Local Name at all, but only use Local Class when searching for an appropriate contract. The EUREX instruments I use all seem to have a different local class name for monthly/quarterly expirations than for the weekly ones. No mix-up between quarterly and weekly contracts is happening. Once an appropriate contract has been found its conid gets recorded in a file and from then on only this conid is being used in my software. The EUREX instruments from your list which I use are: ESTX50 (2x), V2TX, GBM, GBL, DAX (3x), GBX, plus additionally GBS and DJ600.
As a first shot: yes. And then let your system run for a couple of days/weeks and see how your position sizes develop. And thus how much you would actually need in cash to fulfill margin requirements.
Users of psystemtrade - this problem now fixed for the two contracts where it has affected me (local names MSCIWORLD, MSCIASIA). Rob
Automated trading is no less time intensive than discretionary trading, the only difference is you sit in front of a computer coding instead of in front of a screen monitoring, if you think it's set and forget it doesn't go well. That's why we have automated arbitrage that produces much better results which people layer their bots over (hedge funds and students being mentored), the results are more stable and quite spectacular like this. I can already tell you that your any other solution results will be losses equal profits hoping for a large profitable trade, except you will have a large loss trade, your loss trades must be 10x smaller than your profit trades which is what our arb does.
Okay, will do, thanks all. By the way I just noticed this on the IB page where they brag about paying interest on your excess cash: "Please note that interest is earned on positive settled cash balances held in the securities segment of an account but not on cash held in the commodities segment." (https://www.interactivebrokers.com/en/accounts/fees/pricing-interest-rates.php) Does this mean that my excess cash in my futures account will lose out on this 4% interest?
If that question is directed to me: I might be insufficiently qualified to answer that. Your IB account consists, under the hood, of two segments: securities and commodities. IB has some mechanism in place to daily sweep cash balances from one to the other. This has to do with your margin requirements in each of those segments. I do not know in detail how this sweeping works, and what the impact is on the debit/credit interest on the cash positions. It is one of the things I don't calculate myself, but simply accept what IB prints on the monthly overviews they send me.
