Because I’m sure you’ve all been here – I have spent all day NOT understanding why:

Buy = Ref(Buysetup,-1) AND High >= (Buystop,-1);

….. was returning an error message relating to the , in the (buystop,-1) section.

Finally figured out that if I removed the comma it comma it worked – meaning that syntax was thinking it was looking at a number, but the ,-1 bit was asking the code to look one day back.

The missing REF – ref(buystop,01) fixed the problem.

All day, friends. All day.

OK so time for an update

1. Progress on the course
So everyone has their own learning style, and mine is generally learning through doing. I’ve worked my way through reading through most of what is coming up, and am now back to the start, making notes for myself to refer back to as I go. Lots to do. Love the structure that I’m encountering, feel like it’s going to take a while to absorb it all.

2. Trading update
November 2021 +17.4%
December 2021 -7.2%
As mentioned above, to this point in time I’ve been an early stage / Series A investor, and my current market performance is heavily tied to two listed companies where I am escrowed – one until November 2022, the other until July 2023 – so not much I can do other than improve the rest of my skills…. hence the course.

3. General thoughts
I have a leadership role in a large healthcare organisation so the period of time ahead is busy, and the learning associated with the mentor course is a pleasant distraction if nothing else. And of course, it’s a lot more.

All the best everyone.

Sorry been busy with C19 in WA.

Trading update:

De 2021 -7.2%
Jan 2022 -11.1%
Feb 2022 -5.7%

OK, have spent much of the last week thinking about a weekly momentum based ASX 100 system – which I’m sure many of you have done before. Thanks to Nick and Craig for the assistance so far.

Some thoughts as a reminder to my future self:
1. You can’t beat putting the hours in with AB – it’s not intuitive if you aren’t using it a lot. Also quite unstable from time to time. The “MAINT” icon bottom right means something. Yesterday I just couldn’t get the system to look at the right data – reinstalled AB; also re did the data from NDU and all in all it worked.
2. Building a momentum system is really about the balance of trying to get a system that does a sufficient number of trades; gets you out early when things go bad – but not too early; and lets your winners run. Or at least that’s what it seems to me.
3. I wonder how difficult it is to convert the back test results into real life. And when I say that, I assume it’s difficult not the other way round.
4. Even in my best years on back test, there are many negative months.
5. If I include time out of the market due to market filter, the longest run of non positive results is 9 months. That must feel like a long time.
6. In a series of 300 months: 1 had a return of -11% (0.3% of months); 23 had returns between -5% and -10% (7.6% of months); 75 had returns between -0.01 and -5% (25%); 45 months out of the market (15%); 105 months with a return between +0.01 and 5% (35%); 36 months with a return between 5% and 10% (12%); 15 months with a return >10% (5%).
7. I wonder what rookie errors I’m making.

Anyway, that’s today’s update for future me.

Pleased to report that I am now the proud owner of an ASX100 based weekly momentum system, plan to slowly scale into positions over the next few months.
