One has to wonder how it is, that seasonal trends in previous years, seem to be in competition with the algorythmic trends in high frequency trading. And almost rendered null.

I have noticed in day trading, that there are certain times (nearly every day) when a market will make a sudden move, sometimes with, sometimes in opposition, to the trend. Afterwards, the markets return to a somewhat directional (in trend) slow and steady movement. And I've notice that this in several markets, not just a few.  Tends to mess with the indicators.

I hadn't noticed it.  I'll watch for it.  

Perhaps my approach is a bit longer than intraday but I have found charts look the same as they always have.  It is people who program the computers, no?

The 1987 crash was pre algos.  Markets do crazy things sometimes.  I hesitate to ascribe it to machines.  When the market got crazy volatile in early February, the pundits were saying it was because of some option derivative products.   I am skeptical.
