the mindset of trying to nail the top or bottom killed so many good trades for me in the beginning! i would be up good but wanting every dollar then a reversal happens and your now down again.. i take profits and move on to the next one!!
Today as an example, got in the morning for 20% on puts, sold right above an important level. It reversed on that level for a pullback but overall looked down so reentered at resistance, made another 40% on puts again and sold right above that same level. See you tomorrow!
