Bid - Ask Spread on Options

I have a general question about the bid-ask spread on options. When you are going to make a purchase what is the maximum difference for the bid-ask spread that you would consider acceptable? There are some stocks with nice movement that consistently have bid-ask spreads well north of $0.30 but usually around $0.50 to $0.75. Should I consider these stocks as non-tradeable?

Thanks!

Took REGN and put it in my basket. Looked up options. Spread $2+. Took REGN out of my basket.

On average my spreads are .30 or less...I seldom get into spreads higher than that.

If you want your spread to be less on a fast moving stock wait for a pull back then get in. However make sure a pull back doesn't change your signals for an entry.

I think the rule was to only trade options with big spreads off big charts. You should not trade an option with a big spread off small charts.
