A lot of traders are trading with no money.
Basically in Singapore, you have a three-day period before you
need to pay the stock. It work like this:
Day 1: price is 650 cents, you buy 30 lots = $19,500
Day 2: price is 652 cents, you hold
Day 3: price is 655 cents, you sell 30 lots = $19650.
The gain is $100 (exclude trading fees)
You need to pay up on the third day, but you have already sell
the stocks, so you gain $100 dollars without having real money to
invest.
The above is a 3-day trade. Some people do a 1-day trade.
Others, you can also borrow money from the broker firm to
trade,then you need to pay up within 20 days.
Trading and investments are two different things. The former is
a job; the later is a investment.
