100% agree with no more of the "too big to fail" crap. But have to disagree with betting the company and going broke - thing is it wasn't his company. Yes he was the CEO but the shareholders own the company and I'm certain they are not too happy he was betting the company on Italy MMS

MF Global Didn’t Segregate Client Collateral ... damn it doesn't look good here. Sorry to hear you had an account with them. If this is true there *better* be jail time. thx MMS

For his stellar performance at MF Global, Corzine will receive around $12.1 million in severance, according to the New York Times' business blog, Dealbook. This should light a fire under the Occupy Wall Street protests. MMS

Many traders believe there's a system that can pick tops and bottoms in prices. In fact, a whole technical analysis industry is built on these theories. On the other hand, value investing is about knowing the value of a business and paying less than that amount. The difference between the value and the price you pay is your margin of safety (or margin for error). What does everyone here think about value investing? Do do you do it? Is it an IRA-only strategy? Do you use it in conjunction with active trading? thx MMS

Thanks for the offer ... there are lots of questions people are already asking in the other threads ... why don't you start by answering those? thx MMS

Well it has happened ... betting the company on european sovereign debt will do it to you. MF Global goes bankrupt, is 1st U.S. casualty of European crisis

Type defines the properties\functions\events\etc of an object - like a blueprint. But an object is an instance of the Type - like a house. Maybe another analogy will help here ... tsdata.trading.Order == 'Human' MyOrder == 'Mark' So MyOrder is an instance of Type tsdata.trading.Order just as 'Mark' is an instance of Type 'Human' So therefore you can call 'MyOrder.Cancel' just like you can call 'Mark.Walk' But 'Human.Walk' doesn't make sense because 'Human' is just a definition. 'Mark' is the instance of that definition. Thats why you can't call 'tsdata.trading.Order.Cancel' MMS

Events allow objects to notify other objects about its state. You use events when you want to be notified when another objects' state changed (e.g. OrderStatusUpdated). At that point, the receiving object can get all information it needs from the event arguments or from the sender of the event. MMS

More accurately, the MyOrder variable is set to the output of the OrderTicket1.Send() method. What is happening here is the OrderTicket1.Send() method returns a Order object and you are setting MyOrder to point to that object. These are 'events' that are initiated by the object What this is doing is registering the OrderStatusUpdate 'event handler' (that we talked about in the previous post) to the event MyOrder.Updated. So whenever the Updated event (on the MyOrder object) happens, it will call the event handler OrderStatusUpdate. thx, MMS

Yes it usually works like that The sender can be any object that initiates the event. And a receiver can be any object that chooses to listen for the event. Remember, in OO, all functions\methods are attached to an object. So 'event handler' is just a specific function on an object that contains the code that responds to the event. MMS

This method is called an 'event handler' (I can tell by the type of the parameters - tsdata.trading.OrderUpdatedEventArgs). An 'event handler' is the method that runs code when the 'OrderStatusUpdate' event happens in your program. These parameters are common to event handlers, as it tells the receiver who triggered the event (elsystem.Object sender) and if there are any arguments for the event (tsdata.trading.OrderUpdatedEventArgs args - this would be data, etc). In this particular example, the parameters are not used but more often than not, these parameters would be used. MMS

A namespace is used to organize Classes. In large systems, there may be many classes what would have the 'name' Order, so to differentiate between them, you put them into its own 'namespace', which is 'tsdata.trading' Remember my first post about OO being a way to organize code. This is a real-life example of that. To use the correct Order class, you have to declare the correct one by using its 'fullname' - which would be tsdata.trading.Order. So yes to your question. No, 'MyOrder' is simply the variable name. A variable must be declared to be of a type, most commonly an integer or a string. But here, it is of type 'tsdata.trading.Order'. So 'MyOrder' is a 'tsdata.trading.Order' I hope my explanations are clear ... some references: Introduction to Object Oriented Programming Concepts (OOP) and More - CodeProject thx MMS

Wow - losing 90% of market value since he took over. Wonder how much many millions he got paid to for that spectacular perform. And they're thinking he might take over as Treasury Secretary?! Oh I fear for the USA. MMS

OO is not a new programming language - it more like a new technique of how to use a programming language. C# is a OO language but you can write a program that is 100% procedural in nature. So if it was written in EasyLanguage, you just have to get your head around how they organized the code, and if they used any OO features of the language. You don't have to learn another language. I hope that makes sense ... MMS

The A Look at a Stock Trader's Day thread is a look at how a stock trader structures his day. I wanted to highlight this part: thx MMS

The put-call ratio is primarily used by traders as a contrarian indicator when the values reach relatively extreme levels. This means that many traders will consider a large ratio a sign of a buying opportunity because they believe that the market holds an unjustly bearish outlook and that it will soon adjust, when those with short positions start looking for places to cover. There is no magic number that indicates that the market has created a bottom or a top, but generally traders will anticipate this by looking for spikes in the ratio or for when the ratio reaches levels that are outside of the normal trading range. MMS

I could see a vendor building the code this way - where the instrument (stock, etc) is the object and things like volume, price, etc. are its properties. e.g. class Stock() { // variables to hold data int LastHigh; int Close; int Price; int Volume: // properties to return calculated data values bool NewHigh { return Close > LastHigh; } } Then someone would use this object like so: Stock s = new Stock("AAPL"); if (s.NewHigh == true) BUY!! So it all depends on the framework provided by the vendor. I know NinjaTrader is built with C# so if you program against it, essentially you are using OO. But like Tams said earlier, if the main goal is Trading, it doesn't matter whether it is OO or not, the tool doesn't matter. You just want it to work. thx MMS

This applies to programming in general but understanding and being able to program something using recursion. Once you understand this, OO becomes much easier as you are now able to think about objects\reuse\etc in an abstract way. Too me, basic OO is just a way to organize data\code into useful, self-contained things - called objects. So instead of having 10 variables and 50 procedures\functions in a file, instead you have 5 objects each with 2 variables with 10 functions\properties each. So coding and understanding this is easier as you are breaking the problem down into something smaller and more manageable. Now there are advanced features of OO that took some more practice, like Inheritance and Polymorphism. These features are there to help reuse code. Summary: 1. Objects - used to organize code\functionality 2. Inheritence\Polymorphism - ways to reuse code and reduce copy\paste I would say a common mistake is for people to 'over-engineer' their object hierarchies and incorrectly implement Inheritance and Polymorphism. I've seen OO programs much more damn confusing than a procedural programs. It all depends on using the tools correctly. OO gives plenty of rope for people to hang themselves with. But given the complexity of software today, some applications would be nearly impossible without OO. thx MMS

NinjaTrader is written in C# (C-Sharp), a powerful object-oriented language that runs on the Microsoft .Net Framework. It allows your NinjaScript to do a lot more than any scripting platform just for trading. The downside to all that power is that it may be harder to learn. Great for programmers, are you a programmer? If you want to get trading quickly, I TradeStation is a better bet but the downside is you are tied in with their brokerage. Not that its a bad thing but its something to consider. There are so many variables, what is most important to you? MMS

Trading decisions are based on all the variables involved, not just the stock's price movement. One variable, of course, is the time frame the trader is accustomed to. If you are a short-term, high-frequency trader, then you may choose to take small profits, or losses, several time per day. If you look at multiday time frames, then you should set price targets, for profits and losses both. MMS

Great idea ... I'm a programmer by trade so I will be more than happy to help and answer questions ... bring them on! MMS
