7/8
The verticals was a good trade. I was correct about the direction. The RUT broke down to the 480 level from about 500.
I managed some good yields on the trades.

I closed a small portion of the puts for a $2.00 debit for a $1 gain (1/7 =+14%)
The trade is in a better position since it is further out of the money and I can have decay work in my favor.

In response to Mark's comment that I miscalculated the probabilities. I used a quick way of calculating the probability of sucess as:
Risk/width of strikes (7/10), which gives 70%. This is what ThinkorSwim has been teaching in their online chats/classes and also in the latest issue of ThinkMoney.
As of today at the close the 520Call has a delta of 36. The probability of expiring is 34%, which is close the delta. In other words 100-34= 66% is the probability of success. This closely matches the 70%. Here is the picture:


The risk graph analysis shows that by July expiration it has a 67.21% chance of the RUT below 520 and 32.79% closing above 520. I think that this matches the quick and dirty way of estimating the probabilities of success.

To answer your other question on the -25% loss: It would be 25% of the credit and not the risk. So it would be 3*.25=.75. I got this idea from Dan Sheridan's webinars.
6/25
TRADE SETUP: SOLD -1 VERTICAL RUT 100 JUL 09 520/530 CALL @3.00 ISE, RUT MARK 503.15
Net Credit =$3.00
Max Reward =$3.00
Max Risk =$7.00
Probability of Profit =70%
Profit TARGET: 20%
Loss EXIT:-25%
TRADE MANAGEMENT: Need to monitor the trade if it reaches 25% loss. Will exit if it finds support in the 480s.
Did I plan my trade & trade my plan? -

You are making a serious error in the calculations.
1) The Jul 520C has a 42 delta. That the probability of its finishing OTM is only 58%.
Where are you getting the idea that the probability of profit is 70%. {I didn't calculate the delta of the hypothetical Jul 523 call, but it's more than 30.]
2) If you planning to exit when the loss reaches 25% [25% of what? the $7 maximum?] then the probability of success is MUCH less than your 70%. Obviously if you exit, you have a loss.

Mark, I posted a response.
I'm interested in how you calculate the probability of success for a vertical spread.
I calculate it as the Riks/Width of spread as a rough estimate.
