Let me summarize what I´ve learned about LONG STRADDLE TRADING SO FAR.
LONG STRADDLES ARE SEDUCTIVE. WHY?
They are non-directional. The market can gyrate around and sooner or later you will win with a long straddle. They are also limited risk and unlimited reward in theory.
In reality I have found LONG STRADDLES to be slow performers and the returns are about the same as credit spreads. 3% to 5% thereabouts. You are probably looking at a blind LONG STRADDLE taking a month, or three weeks to return you 3%. A lot depends on the VIX reading. Over VIX 25, long straddles work quicker.
Going in blind on a LONG STRADDLE, only requires that you
a) buy far enough out in distance, 3 months, or leap options, to make money of some sort.
b) That you pick a time to enter, when the market is quiet and volatility is low. Kind of like congestion periods in the market with no trends.
You will make money going in blind, at least once a month on a LONG STRADDLE. Your return though, is small about 3%.
If you look at it as 12 monthly trades of 3%, you will make 36% gross for the year on your savings. Pay the IRS their 40% at the end of the year and your savings will grow annually 21.5% net income. This presumes you invest ALL your savings in trading a monthly LONG STRADDLE. Better than the bank right now in 2012.
A LONG STRADDLE PRETTY MUCH has to move 3 strikes in the QQQ index to make that 3%. Each month the QQQ moves about 5 strikes.
The losers in using LONG STRADDLES are the short time traders. Sometimes they win, but they often lose too. You have to be far out in months, to give your trade time to work. Just watch it gyrate up and down and eventually you will either get a trend for the month, or you will get a volatility boost from some big moving stock, that has a news announcement, or good, or bad earnings report. AT least in trading indexes.
PATIENCE is the key to trading LONG STRADDLES. That and entering when the market is dull.
The TRICKS to trading LONG STRADDLES ARE:
If you trade individual stocks with a LONG STRADDLE, that is a different ball game, more speculative.
Dont buy a straddle when volatility is HIGH. Or whatever you are trading is trending. Wait until the trend collapses and goes into congestion. You want low volatility for an entry. A choppy dull market is perfect for an entry.
Keep an eye on your Long Straddle, a couple of times a day. Because the unexpected can happen and you get a volatility spike. If and when you should LUCK OUT, and actually get an unexpected volatility spike for some at present unknown reason ( the reason is not important ) Take your PROFIT and get out.
LONG STRADDLES ARE VOLATILITY TRADES. THEY REQUIRE A VOLATILITY PREMIUM BALLOONING FROM SOMETHING HAPPENING.
Some big moving stocks, like RIMM, APPL, or GOOG for instance, have volatility spikes over news announcements, or earnings, and since they are big daily percentage swingers anyway, they can give you a nice volatility bounce and a profit quickly inside of a day.
Some of the stuff recommended on this thread I haven´t tried, or experienced yet. But here are a few of them suggested.
You can GAMMA SCALP a LONG STRADDLE ?
If you should be bothered by TIME DECAY, because you bought too short in your months, first or second month options, you can finance that TIME DECAY with a 6 strike OTM Credit Spread.
For the GREEK afficianados, Vega reading may be helpful.
One large FUND MANAGER says she ( DerivativeG on here ) trades LONG STRADDLES SUCCESSFULLY.
The problem with option traders in a general sense, is they are adrenaline junkies. They do not have the patience to trade successfully. Plus like the pilgrams that went over the CHILKOOT PASS during the KLONDIKE GOLD RUSH in the 1800´s, most of the time, they are consumed by GREED and GOLD FEVER.
