KIS is the secret to success in trading ; Knowledge, Intuition, Skill. Knowledge can be gained both by reading & by doing a lot of trades. When u do plenty of trades, not only knowledge increases, but intuition & skill too will improve. What people normally do is , they open a demo or real account , & risk , lets say, 10% per trade. , blast the account to zero, get frustrated & opens another account & blasts that too or even quit trading. On the other hand, if that person had risked only 1% per trade, he would have given himself oppurtunity to trade atleast a 100 trades in that account, thus he would have improved his knowledge, intuition & skill from those huge number of trades, instead of getting frustrated & leaving trading.
