Using Algos Intelligently

I have a bunch of algos that I run on different markets. There are a number of algos for each market and I use the one that is appropriate to the context.


How do I know in advance which one to use? I can't know for sure but that doesn't matter because each algo I have is historically profitable over time.


Some algos are most profitable in very trending markets, others are better in more choppy days.


I manage my algos just as I manage my trades. I know what announcements are due during the week. I know when we are in earnings season. I know when the Fed will talk. There are lots of things I can know in advance if I do my homework.


I turn on the algo that I think will best suit the vision for the day. I also break down the days into three time zones and may have different algos, or the same algo with different settings, running during the day. If my vision is wrong I can switch algos.


The strength in running algos is that I can be more diversified and do not need to be glued to my screen.


Having the same algo with the same settings running all the time can be profitable but nowhere near as profitable as doing the extra work to mine the data so a more intelligent use can be made of the algo.


Today's DAX during U.S. RTH was trading in the smaller range as has been the case recently. I've reduced the range bars to fit the volatility.
