I wish I was able to find the optimum time to enter each spread but I try and avoid market timing as much as possible. When I want to place a trade based on time to expiration and the strikes I simply commit my capital to the trade. If I try and place a little at a time guessing on price swings to get better fills I could either miss out on what was an already good premium or be forced to chase the market and go after strikes I am not comfortable with.
I expect the market to have price swings and I choose strikes which I feel will not be affected by those price swings. I would rather not try and place my spreads at what I think are good entries since I am more likely than not to mis-time those entries. I prefer to set and forget the positions.
What happens is that I feel if I try and get too cute with my timing, I will have more cash/margin on the sidelines doing nothing when I could have simply entered the spread and let theta and the index do its job.
I always have cash/margin in reserve so I can always add positions here and there when I want. For example, for December I still have a lot of margin available for more positions if the market presents the opportunity.
It is best summed up in your quote:
"At times this works well and at other times I've missed some real opportunities to get a good credit for an OTM spread that then goes even more OTM."
I would rather not play that guessing game and simply enter my positions at the strikes and time to expiration I like. I spend most of my daily energy in the S&P and Russell futures lol.
But I have to say take this all with a grain of salt because this is simply my approach, not necessarily THE right approach. If you would prefer to scale in to each expiration month and you find it works for you, then by all means you have to do what you feel most comfortable with.
Quote from rdemyan:
Coach:
I've noticed that when you place a trade, you, more or less, commit a large amount each time (typically 50% or more of the margin you've set aside for credit spreads).
I typically commit maybe 10 to 20% at a time. My thinking is that if the market moves then the next credit spread or IC will be relative to what the current SPX price is.
At times this works well and at other times I've missed some real opportunities to get a good credit for an OTM spread that then goes even more OTM.
Of course this is hindsight is 20/20 and, of course, each of us has their own style.
My question is why you commit as much as you do at any given time and why you don't spread your entry points more in a manner similar to what I've mentioned above.
