My view is the IWM is now hitting its resistance, and should go down a bit.
So for July options i will go for
Sell to Open 145/147 Call
Sell to Open 135/133 Put
I will consider to Sell to Open 145/147 Call first and then wait for opportunity within 7 days after enter call spread,
tp leg in Bull Put Spread 135/133 for better premium.
I might or might not trade this monthly position, unless i have some other weekly spread position free up my margin.
Trade with care, and make sure you dont enter > 10% of your capital for risk management to spare cash in cash you need to repair position later stage.
