    Oanda No Limit Orders

    What scalperboy described above seems like a serious issue with Oanda platform. Bound orders or not- there is a well-defined and expected behavior for limit orders, and if a trading platform does not/cannot implement such a basic thing - I would think about switching to another platform.

    Java 8

    It depends on your level of experience with programming in general and Java. I would go to amazon.com and read the reviews for java 8 books.

    I can only get 2 days of 1 minute historical data from IB?

    I can only get 2 days of 1 minute historical data from IB?

    1. API is the most convenient way to get historical data. There are a number of limitations that can be overcome with clever programming that make it... not very straightforward... to collect data for longer time periods. 2. NO. You can only get 1-min data for 2 days IN A SINGLE API REQUEST, but...

    How to implement communication between mt4 and external app

    If your external application can expose RESTful Web Services (text over HTTP) - you can use windows socket API dll's to invoke those web services. I've done something like this in the past- if you are interested - send me a private message.

    Daytrading: Should I consider other software than NinjaTrader?

    If you don't need API/programmatic access - why not just use ThinkOrSwim from TD Ameritrade? It is probably the best charting software available to retail traders.

    R or Python for someone with elementary CS skills?

    You need scalability if you need to execute a lot of trades (lets say at least 100's an hour), or monitor/trade many instruments in parallel. Python does not provide a good way to build multi-threaded or near-real-time "back-end" (non-web) applications. Also, because of the lack of strong typing...

    R or Python for someone with elementary CS skills?

    MetaTrader uses it's own language - MQL, which is similar to C, but takes care of memory management. Other than that - you could write your algos in Python or another language, and integrate with MetaTrader via DLL or web services... R is a good choice for prototyping , use it if you have a...

    Operating System Choice

    I have to admit - Linux is a good OS for technically-savvy people, not ready for mainstream. However, using Windows compared to MacOS is like driving a steam-powered 1890s carriage vs. a modern car... It's just an outdated and user-hostile operating system.

    Cost of trading ETF's?

    I would recommend to stay away from trading commodities using ETF's over long periods (more than a few weeks), unless the market you are trading has an inverted futures price curve. In the normal market, where longer dated futures are more expensive than near-month futures ETFs typically have...

    My breakout trade in copper - how can do better?

    Yes, breaking BB band by itself is by no means a buy or sell signal. It is, however, a signal that attracts attention to investigate the market, especially when a BB band gets broken decisively on a weekly chart. I do agree, that making money on intra-day charts, especially on so short as...
