Selling pressure is building in the S&P and using cheaper OTM put options is an excellent way to capitalize on the increasing pressure. Buy OTM put options with deltas around 20-25 and scalp the gamma value, you will only need a small downside move after entry and set a limit order to automatically close the position at the desired profit level. Here is an example in the SPY using the $170 strike price. (not real values but close)
Desired net profit $100 Dec. 170 Put options, Est price.50 cents Deltas: 22.25 Gamma: 3.72 (net scalping value) #number of contracts: 27 (rounded up) Est trading cost per share: .02 cents Gross gamma value rounded up: .06 cents Est negative SPY movement to achieve desired net profit: .27 cents %of movement to 5 day average true price range: 22%, low percentage, high probability of profit Entry price at .50 estimated Limit to sell at .56 Gross profit: $162 less cost: depending upon your trading platform Net profit: Should be $100 and possibly more depending upon your commissions
That is how I scalp the S&P using cheaper OTM options up or down.
