Hey guys,
a lot of my intraday automated trading system stopped working
this month across indexes and commodities.
anyone experiencing similar things like me ?
Any idea which historical market period is best to compare to the current one ?
Considering we're really talking about "unusual" or "extreme" volatile time period...
Why don't you just pull up a weekly or monthly chart of the
VIX. It's easy to see similar volatile historical market periods although their
reasons for the extreme volatility are different. Some of these extreme volatile historical market periods have similar like reasons while others do not...all of these reasons has absolutely nothing to do with technical analysis. Its mainly just geopolitics, war (armies or currency), debt crisis, FED/IMF/ECB decisions, global economics, temporary trading rules that causes fear amongst those that have the greatest impact on the markets, illegal trading activities and many other none technical reasons.
Most data sources go back as far as year 2000 while others go back as far 1986 when the VIX first started although the professor that designed it actually started computing it I think in 1984 or 1985. I remember because when I was a kid my old man was a floor trader at the time, a few of his buddies were over at the house playing a big game of high stakes poker...they were calling the VIX a game changer.
Just in case you are curious, the biggest historical volatile period (since 1980s) also began in
Asia. I'll let you pull up a historical VIX chart to determine the dates for such (your homework).
Oddly, in the recent situation, many were concerned about Greece while forgetting or underestimating what was brewing in China. I know a few algo traders that begin adapting (making adjustments) about 2 - 3 months ago.
P.S. I'm not an algo trader.
P.S.S. I know a PhD guy that calculated his own custom VIX going all the way back to the late 1800s (1890) when exchange data became more accurate due to changes in technology. Reasons I mentioned above are primary causes for dramatic (volatile) changes in the markets.
