makes sense, thank you for the clarification

@globalarbtrader can you please give us the rational, why you think the dec future is to near, what is negative about trading that near contracts?

currently 2nd and 1st are in backwardation, so would you recommend to buy it now? look here: http://vixcentral.com however: when you look at the chart of the vix futures of the last few months you see, that the roll yield is very high, that means you have to sell the cheaper contract and buy...

The real world implication gets bad, when the productivity growth is lower than the interests, which needs to be paid. Look debt service is in most industrial countries, the seconds or 3rd largest budget position, in the current fiscal year us paid 423 Billions on interests alone...

You are right currently USA has about 19 Trillion debts mostly (about 13 Trillions) are domestic debts, that means investors, hedge funds and retail investors buy the treasuries. China holds 1,3 Trillions and Japan 1,1 Trillions, and 3,8 Billions other countries like (Arabs, Europe, etc). You...

Just for fun, you also have a 100% expectancy when your first trade is 90% loss and your second a 190% winner, do you want to guess what your balance looks like. Some martingale systems work great, until you are killed of course, then they don't.

any prove or comments why you think this is a good idea?

there are more, look here: http://www.gazprom.com/investors/creditor-relations/bonds/

thank you for the correction, to remember the Greeks: Theta => T ime Vega => V olatility Gamma => Gas (acceleration) of Delta Delta => Delta per Underlying change I know the last one is a little bit lame :)

Is IB save? Generally the questions is answered above BUT what about some crazy sanctions against Russians in the future. You never know. So even with brokers you might consider diversification, maybe an Asian or European broker, but I can't give any advice on that but consider your risk.

Go one step back, the Greeks are derived from the Black-Scholes formula to calculate a fair value of an Option. That means every time a Greeks changes the price of the option also changes. when comming to practicalities for beginners, consider vega, delta and gamma. Vega tells you how much the...

We are currently in very troubled water: very strong gains in almost every instruments for the last few years, prices for houses are much higher than before 2008, interest as low as the can be, national debts are about 100% of GDB for almost all western countries. I don't see any save heaven...

The tool/language to do a quick back test is your smallest problem, the theory you need to know is a much bigger dragon.

Bonds are not really save. What will happen, when the interests go up by 1 %? Your bond will go down. Bonds are not a save haven in a very low interest phase.

One more thing to consider: What are the big players, e.g. Hedgefonds are doing, this give you also an idea, what to look for. You will not find a system, but still its funny to see, that there are fonds investing all the eggs in one basket. Others invest most of the money in 3-5 Instruments. I...

Most of the discussions we are talking about naked put / calls. What do you think about selling spreads, where the risk is reduced, though the the reward is also smaller. However you would still have some kind of buffer if you are wrong.

most of the times, when it comes to trading it's like going to the moon: for a naive person it seems not a big deal, it does not look very far away but still he will never succeed. On the other hand with a proper research and much development it was possible, hard though. The moral of the...

1) use a bundled Python like Anaconda, it is easy to install and almost all needed packages are included, especially when you are using Windows. 2) Use Jupyter Notebook as your development environment instead of Notepad++, because you can execute one line after the other and see the effects...

If you are a seasoned programmer you can do everything in your language, this type of guys are seldom changing to other system, I hear people talking all the time of the benefits of vi and emacs as an IDE :))) But for the rest of us, the not professional programmers, not even nerds, Python is a...

@M.ST. Lastly I wanted to tested an Open Range Breakout system for SPY, therefore I would like to check, when a high or low of the day occured for every 30 minutes. Analyzing this in Jupyter took me about 10 lines of code, the result is a graph, check the attachment. This is the Python /...
