Trading Stocks (equities), I go to cash at the end of the day 90% of the time.
I hold trades (short or long) over night in key situations when I see the opportunity.
The reason I go to cash at the end of the day is simple.
The strategic release of payed for analysis or news, with the intent of moving a stock or the markets in a direction a particular group wants, has become SOP. This has always happened on Wall Street, but lately it has been extremely bad and more obvious. I also trade high volatility stocks that trade in wide ranges daily, they can gap up or down drastically over night.
I consistantly make money each month doing this. I used to hold more trades over night or longer, when I stopped doing this I now make 6 figure money on average monthly instead of 5.
Each trader will have different methods that work for them. Do what works for you.
I trade 1000 to 5000 share lots intra-day based on Technical buy/sell or short/cover points. I do not try to pick the exact points, I use a range. I use reserve orders almost exclusively except when i want to be the MM.
I wish you success in whatever you do.
PS: I want to add that trading is not gambling. I see a few references to this in some of the posts here. If you have the mental outlook of a gambler and you gamble in the markets they will eat you alive. Trading is a skill, as you see above I did not wish you luck, i wished you success, because luck has nothing to do with trading.
