Actually the losers are 2.5 as those are 5-point spreads so your max loss is 5 pts minus premium received.
Hi Wayne, I was wondering when someone would ask about the martingale, lol. Mine is what I call a modified martingale. Here's what I do. Start with one unit. After a loss, increase to two units. Stay at two units until you have a net two winners, they go back to one unit. If you have a net two losers at the two unit level, increase to three units. Again, stay at the three unit level until you have a net two winners. Then drop back to two units and proceed, as above. You would increase to four units if you had a net two unit losses at the three unit level, but that has never happened in ten years. Sounds a bit complicated, but it's really quite simple in actual practice. It's been a big winner.
Thanks. Yeah I'm certainly not against increasing size (carefully). It's been good to me too. A "standard" martingale double-down will eventually bite you. In the markets, unlike Vegas, oversold/overbought conditions create opportunities. Yes, you are "due" for a winner after so many losers. But you still hafta be real real careful...
On a similar note to me, I real time traded a system in 2008 and 2009 that yielded returns that anyone here would be thrilled to achieve but as of today has yielded only 8% this year (real time). Time to look for a new pattern?
I've never utilized a Martingale but if I was faced with doubling down (or some variation) after a losing month or two, I'd slightly ratio the long side, willing to take a little longer to breakeven to the upside but assuring me of lesser loss to the downside if a buzzed by a multi-month downtrend ala 2008. Size does matter!
By the way, the strategy that I mentioned was also traded in real time with real money over the last two years, not backtested or paper traded.

Interesting information there - I honestly wouldn't have guessed that the market had been up in these time frames more often then it has been down despite the overall drop in the market. What I would be curious of and would be interested in backtesting would be if there was a way to improve this especially for the really bad months - I think that trying to always close early and not having to pay the full $5.00 to close isn't quite good enough because of potential large drops and the fact that if you close a bit early, the market might roar back near the very end and would have saved you. My thought would be to add extra puts to the protection side and in the more extreme months (maybe the 5%, but especially the 10%+ months), maybe you could actually profit on the downside. I am more used to using SPY options, so an example for me would be like if you were doing this today: Sell 10 SPY Dec 123 Puts Buy 15 SPY Dec 118 Puts or maybe something like: Sell 10 SPY Dec 123 Puts Buy 10 SPY Dec 118 Puts Buy 5 SPY Dec 116 Puts or whatever - this would obviously bring in somewhat less money each good month, but could help out quit a bit in the few down 10%+ months. Of course, this would actually be worse if you waited till the very end and the SPY ended right at the strike of the extra puts you bought (meaning they are all worthless, but you still owe for the shorts). You would probably want to do something like "If SPY has fallen >5% and at least 1 week remains, close the position" or whatever - I haven't tested this obviously, so you would want to go back and review previous months and when to consider closing maybe. Just a thought anyway. JJacksET4
