Quote from Don Bright:
Something to think about: We advise our traders to put on 2 "layers" of any purchase or short sale of a pair of stocks. For instance, if their pre-determined layer size is 200 x200, the first layer should be 400 x 400. Why? Well, the reason we buy the pair in the first place is because the price differential has gotten a long ways "out of line."
When we buy a pair, and it goes the wrong way, it actually becomes a "better" buy, based on our analysis....so, if were to buy a spread for $4.00 (expecting it go back to $8.00 for example), if it went to $3.00, we would buy another layer. Not so much "averaging down" but merely taking the opportunity. But, we added a layer nonetheless that was going against us. This, by definition added to the risk, although a risk we are happy to take. We usually limit our layers, based on certain info, to about 4 layers. And have no problem getting the total position to a size we can still handle, and trade from. Buy at $4.00, buy at $3.00, buy at $2.00.. sell at $.4.00, sell at $5.00, and sell at $6.00 vs. waiting to get all the way to $6.00.
My main point, the reason to buy 2 layers to begin with, is..... if we are adding when it goes against us to maximize profit potential, what happens if we merely buy 1 layer and then take it off for a $1.00 profit, when the spread may "trend" up another $5.00. So, we buy two layers, take one off at the pre-determined $1.00 profit, and let the other one ride.
So, perhaps, this might be an example of scaling out..... FWIW.
I haven't posted to this thread in a long time... kinda surprised that it is still so active.... IMHO, there really is no "right" answer to the question since we base our entries an exits on so much outside criteria that we take partials off as part of our overall plan.
Anyway, something to think about guys...
all the best,
Don
And on the pairs that begin moving in the right direction immediately, then you don't have full position on for the full move. No--it's best over the long haul just to get in with full position on every time.
