One trick I employ is using my overall portfolio value as a gauge in the market as a whole as well as to how I am trading. In the long bad 05 period my account fluctuated between $80 and $100K with the market correcting each time almost exactly at $100K. It was more than coincidence my beta matched up with the overall up and down's of the market & I managed to create my own sell signal. What did I do? I set up a system where at $100K I took $20,000 out and spent it! By pruning I raised funds at market tops. This was during the period when we always seemed to be going back to DOW 10,000. Then we had our recent run and the account and the markets broke free.... the rest as they say is stoney history. Now a correction and I lost a lot. But I stay fully invested and rotate and buy my way through corrections- that's why brokers love me! I call when no one else does!-- and now I have another indicator-- my account is within One Thousand Dollars of Being back to where it was before the dive-- not bad when you consider the DOW is 400 pts away! This folks I HATE TO SAY IT-- is a SELL indicator now and I have to have a long deep discussion with my soul. But I just thought I should let you know when things get overbought and the stoney overbought oversold indicator is flashing a warning sign. peace.
