hey how are the markets usually trade during summer july/august?
As at other times of the year, prices tend, overall, to rise when buying pressure exceeds selling pressure, and
vice-versa.
"Summer" is a geographically-dependent phenomenon: in many parts of the world, it's winter at the moment.
Nevertheless, the overwhelming majority of trading volumes transacted relate to the Northern hemisphere, so the reduced trading volumes of July/August (more so August than July) are fairly reliable.
The extent to which this affects one's trading varies greatly according to the type of trading one does (indeed, more greatly than many people appreciate, IMO: doing fast-moving, intraday futures trading, or "semi-scalping" as some people call it, I typically get fewer trading opportunities in July and August than in most other months, but the overall difference is less than many would expect ... I don't begin to share the quite widely-held perception that "you might as well not bother at all in August because there's no volume worth talking about", but I suspect that some of the subsequent replies to your question may well say something similar!)
