The table here shows the results of the following back test criteria:
- daily MACD crosses down today
- daily 14,3 stochastics crosses down today from above 50
- weekly MACD is in the down position (fast line below slow line)
Four trading days later all 8 instances closes lower. The minimum was 0.5% and the maximum was over 10%. But looking at the MAX gains versus loss over the coming days and weeks, I rarely see anything this strong.
The instances are not that high, but I don't think that means this sample is insignificant. Some studies are rare, with small sample size, but are obviously notable events.
I purchased both a 214 strike Nov 18th expiration put as well as a 214 strike Oct 7th expiration put. Based on the stats, this Friday's expiration certainly could be used as well. The stats are about par with the 2 week stats as far as option % returns expected.
In this case, the past instances suggest a limit order of 160% gain on the put option would produce a very high expected value and win rate. While the sample size is small, I am going ahead and placing that limit order.
I am going to wait for a couple days before placing the limit order for the Nov put. I think the 199 level on SPY could be broken by November.
Trade Idea:
Buy the SPY Oct 7th expiration 213 strike put at the open tomorrow.
Additionally, a short/inverse trade could be entered here. Using a 7.75% limit gain order and stop loss order (can enter as an OCO if available), would produce the maximum expected value based on the past test.
