Welcome AIMS, Re: My trading methods.................
Generally I know at what price my next Buy or Sell order will happen that meets my minimum requirements. So, as the price/share closes in on my target price, I'll enter an order on a Good 'til Cancelled basis at a Limit price a dime or a quarter better than the actual calculated price. (That extra covers commission cost)
Then I head to the garage to work on one of my cars or to the lake for a swim.
I don't usually buy more than once in 30 days. That helps to conserve cash in a longer downtrend. Sell orders I'll take whenever the Price/Share meets my GTC Limit Order price. So, there's no rhyme or reason to the dates on which the trades occur.
The above is the same for individual company stocks or ETFs.
As mentioned by others, I would stick with funds or ETFs.
My strategy is to wait for a security to pull back at least 20 % before buying. I know that seems impossible, but I think it is worth the wait. I have been AIMing for almost three years and I am almost fully invested.
