Sometimes it hurts to sell into strength, until it's on its way back down and it makes you feel like you should have sold more. Think of your shares as an inventory. You can let go of some at high prices, and if you are wrong about selling you still hold more. If you are right about selling at least you sold some and can get those shares back cheaper. Your inventory should expand and contract in this way, plus you will be a market stabilizer because you buy when nobody wants to buy and sell when nobody wants to sell. You have to use the charts to pick your price points and you won't always be right. I expanded my position again at 0066, but we continued to sell off. My next purchase was at 0024, but for twice as much. The shares bought at 0066 hurts, but my average is somewhere in between. Had another bid at 0021, but low was 0022. The pain goes both ways - hurt when I sold at 0073 on the way up and when I bought at 0066 on the way down. This is why you do it in stages. People talk about accumulation (I'm buying more here because it's cheap), but don't forget about distribution (I'm selling some here because it's expensive). Just my 2 pennies.
PS: obviously know your budget, too. Trading shares exponentially can be dangerous. IE: 100,000 at 0005, 200,000 at 0002, 500,000 at 0001, and then the stock is at 0000 for ten years with a 100% loss on all your shares. No guarantee any stock will "come back"
