It needs sheer dedication, hard work, patience, quick wit and immense knowledge to be successful in intraday trading. Successful intraday trading involves 90% waiting and 10% execution. So, yes, it can make a trader rich in a relatively short period of time if the correct processes are followed, and yes, it is possible to hold on to the profits in the long-term if the correct strategies are followed.
The first 9 successful trades produce $900 in profit. On the 10th trade, when the position is down $50, instead of except the loss the untrained trader purchases more shares at a lower price to reduce his cost basis. Once he is down $100, he continues to hold and is unsure of whether to hold or sell. The trader finally takes the loss when he is down $1,000.
You're probably looking for deals and low prices, but stay away from penny stocks. These stocks are often illiquid, and chances of hitting a jackpot are often bleak. Many stocks trading under $5 a share become de-listed from major stock exchanges and are only tradable over-the-counter (OTC). Unless you see a real opportunity and have done your research, stay clear of these.
