Bigcharts.com said:Parabolic Time/Price
The Parabolic Time/Price System, developed by Welles Wilder, is used to set trailing price stops and is sometimes referred to as the "SAR" (stop-and-reversal), Parabolic SAR is more popular for setting stops than for establishing direction or trend. Wilder recommended establishing the trend first, and then trading with Parabolic SAR in the direction of the trend. If the trend is up, buy when the indicator moves below the price. If the trend is down, sell when the indicator moves above the price.
The formula is quite complex and beyond the scope of this definition, but interpretation is relatively straightforward. The dotted lines below the price establish the trailing stop for a long position and the lines above establish the trailing stop for a short position. At the beginning of the move, the Parabolic SAR will provide a greater cushion between the price and the trailing stop. As the move gets underway, the distance between the price and the indicator will shrink, thus making for a tighter stop-loss as the price moves in a favorable direction.
If you are long (i.e., the price is above the SAR), the SAR will move up every day, regardless of the direction the price is moving. The amount the SAR moves up depends on the amount that prices move.
There are two variables: the step and the maximum step. The higher the step is set, the more sensitive the indicator will be to price changes. If the step is set too high, the indicator will fluctuate above and below the price too often, making interpretation difficult. The maximum step controls the adjustment of the SAR as the price moves. The lower the maximum step is set, the further the trailing stop will be from the price. Wilder recommends setting the step at .02 and the maximum step at .20.
For additional information along with the calculation please refer to "New Concepts in Technical Trading Systems" by Welles Wilder.
fixed fraction of capital ? any other methods?
Currently I have a position on in Bean Oil. Margin is about $200 us. If I was trading double margins that would be $400 per spread. I have suggested keeping $1,000.00 per spread for trading.Given that spreads tend to be lower risk that outrights, does this mean a trader can use a greater portion of capital (and so risk a greater portion) for each trade whilst still keeping a sensible and sustainable money management regime in place?
This is money management. Keep it simple you are already hedged. Stops are “close only,” stops, based on weather or not prices are following the seasonal pattern.I don't think I understand the question.
First, I don't know what the margin or double margin has to do with the risk. Why not using 1/2 or 1/4 of the margin?
Second, why using 1% of your margin account and not 3%, 6% or more to define the risk you are willing to take on each trade.
As you can see, it all depends on your own parameters.
I am not sure if you really need a $200,000 or $400,000 dollar account to take a risk of $2,000.
All you really NEED is the margin. All the rest is up to the money management of each trader.

How can you know where you will be filled, it could be at a better price?It’s clear what is at risk on a single leg position,
The worst is losing your position. Getting stopped out just before the market goes limit up for nine days. When you are liquidating do not underestimate unexpected slippage. There is no reverse slippage, slip is never in your favor.the gap to your stop loss at best and your entire stake at worse.
Still the same. Look at a chart and use stop plus slippage as the risk. Who ever suggested the spread, should have given you a last chance desperate get me out stop. Use one closer. When you get in on Stochastic, within a week parabolic should work well as a trailing stop on calendar spreads.But in spread trading, it’s not so straightforward for a novice to assess the level and size of risk.
Well some multiple of margin is a good idea. Low risk calendar spreads are often under a thousand margin per spread. On something like grains where the margin required can be under a $100.00 you might run a little less.2. On money management, you say to start with $1000 on a single spread trade.
While most traders sometimes find themselves in a spread position. Spread traders in general should not even think about trading outrights. It requires a reckless do or die mentality that is unlike milking the markets, for long term gains. Overall outrights a do not compare to spreads on return on margin (Rom). Don’t trade outrights, if you can help it.Should a spread trader utilize the same sort of money management techniques as an outright position trader?
Yes, take advantage of the low margins and the higher return on margin offered by seasonal calendar spreads.being that a spread is implicitly hedged, should a spread trader take advantage of this?
How much unused capital is in my account this morning?If so, what kind of models do spread traders use?

From this statement it sounds like you are nearly always fully invested in the market. I know you say that you should only trade with money you are willing to loose. But being fully invested is dangerous when trading any other way, clearly have much to learn re spreadtrading.How much unused capital is in my account this morning?

when i mention money management, i'm talking about the management of the capital you have specifically allocated to trading
In which case, your capital should be being used (unless of course, there's no clear move to make).
By "used" I mean it covers the margin requirements for your position plus a bit more for your own personal tastes, I like to have double my margin requirement available in the account.
I am talking about trading spreads. Whereas you are talking about spreadbetting.
Oooppsss It was late, I was drunk, and then I didn't read the thread again this morning....
Look what Jackolan has to say about this.From this statement it sounds like you are nearly always fully invested in the market.
You can’t be fully invested unless you have opportunities. Stochastics does not pop every day. But when it does, why hold back?In which case, your capital should be being used (unless of course, there's no clear move to make).
Preferably take your original capital out, from early profits, then get down to work seriously. You have a dollar waiting on a dime. Get over it.I know you say that you should only trade with money you are willing to loose.
100% of the 10% seems reasonable. Why not 100% of the 100%?In other words, the 10% of money that you've allocated to risky investments is there to do a specific job... to be in risky investments.
Dangerous like when you go home with a strange women, or crossing a busy street blindfolded, skydiving, flying a small plane. What are you talking about dangerous?But being fully invested is dangerous
Excellent!!By "used" I mean it covers the margin requirements for your position plus a bit more for your own personal tastes.
I guess you need a reread of Reminiscences.risk losing all your trading capital .. and having to dig out funds from elsewhere to give you new seed capital for your trading.
Same thing here for seasonal futures spreads.I think you're missing the fact that spreadbetting is a leveraged product.
Euro$ are Time Deposits having a principal value of USD $1,000,000 with a three-month maturity. By putting on a Euro$ spread you control at least a million dollars worth of something. The margin is often less than $300 dollars. Double margins $600.00. That would be money management. You illusionary risk is chart support.If you put on a trade of £1 a point on the FTSE100 at 4300 then you have "bought" the equivalent of £4300 worth of shares. Yet you only need the margin in your account to do this (£150, or in my case, double the margin, £300).
Following along I am putting up the whole $300 on the spread, but actually we are playing with a million.I am "risking" the entire £300 in the account, but actually, I'm really "risking" £4300.
Trade with what you can afford to lose, it hopes of doubling it.Spreadbetting is for money you can afford to lose in the hope of a high reward.
Speculating is speculating.I am talking about trading spreads. Whereas you are talking about spreadbetting.
However, your approach to money management is very different from the ones i have encountered previously, and at present (and perhaps because i am not yet very knowledgeable on spreadtrading) I simply don't understand it, it goes against what i currently know to be key to success in trading. A fundamental factor in trading is preservation of capital - allowing you to live till another day.
Personally i think good money management is absolutely vital to being a successful trader. I don't yet know how this is best done in trading spreads. But as i say i have a lot to learn re spreads and i will find out.
