Thanks for the context.
When deciding whether to sell an iron condor, there are a wide range of possible factors that traders assess. Looking at the deltas of your short strikes are certainly important, as those serve as proxies for probabilities at the time you put the trade on.
There are two main schools of thought re. deltas: many newsletters suggest low delta sales because the win rate is high. The downside is that a bad month can wipe out a year's worth of gains.
For those who feel that the risk/reward ratio of low delta sales is a tragedy waiting to happen tend to sell iron condors with short strike deltas closer to 20. These trades require more frequent adjustments but provide much higher credits.
I'd also suggest looking at support/resistance in the underlying - this will help you define the range and where the asset currently is in that range (similar to what you are using Augen's indicator to measure).
Another key metric is open interest. Large open interest indicates institutional positions and they, more than retail traders, move the markets.
Beyond strike selection, implied volatility relative to historical volatility is a key metric to consider when opening an iron condor position. Keep in mind that iron condors are short vega and a spike in implied volatility, especially as you near expiration, can cause significant problems.
Theta is also something for you to consider. As many options traders know, theta decay is exponential. While theta decay for ATM options is most dramatic in the final 30 days of the contract, OTM decay is most pronounced in the 60-30 days before expiration. This difference allows traders to realize most of their credit without holding the positions through expiration.
Lastly, keep in mind your commissions. Selling a $50 iron condor and paying $10 in commissions puts you 20% down every time you open a trade. High commissions frequently cause traders to hold positions too long in an effort to squeeze every last cent out of their trade which puts you at significant gamma risk.
Hope this helps. There are many ways to successfully trade iron condors but, like most things in life, there are trade-offs.
Your point on vol is valid in my experience -- look at IV and know the range of the given product. For OI and volume -- these are critical measures of liquidity and efficiency. Look for bid-ask spread of a penny or three and volume of at least 1 million in the underlying. Look at something like SPY and AAPL to understand liquid, efficient products.
As for commish, at IB for 75 cents per, or tos at $1.25, or TS at $1.00/contract with no ticket charge, selling a $5 condor one time should bring in say $200 and incur four legs or 4 x $1.00 is $4 for TS or $5 for tos. In simple terms, commish should be considered in terms of the trade price, but even in a four-legged position, it shouldn't be a factor in profitability. Perhaps I've misunderstood your description of selling a $50 IC and paying $10 in commission. In any case, I think it overcomplicates a simple short IC trade to try to understand, let alone manage gamma, just get out by the Wednesday and life is simple -- commish has little if anything to do with a decision to close or roll a position.
