    A Semi-automated system with Python and IB api

    The 'semi' part I am thinking of is, 1) confirmation of entry, as there are times when quantified conditions are met, while obviously not a good time to enter, for example, a rebound after a 30 points run; 2) which exit rule to be applied; this involves some chart recognition, which I am not...

    A Semi-automated system with Python and IB api

    Well, I switched from C# and NinjaTrader (bought their life long license). It is a long story. Ninja can not give all the flexibility I need. And I encountered some error that the support team can not debug.

    Easiest way for a noob to automate entries in Interactive Brokers?

    Well, as for my own experience, I am done with Ninjatrader. I spent some time learning to code in C#, which is the language their platform use. Then, one day, I run into some error that no one can tell why. They have a support team on their forum, some of whom are professional programmers. But...

    Paradox of consecutive values

    So, suppose I have a standard to distinguish between choppy and trendy market conditions. For example when price < SMA(12), it is considered choppy. But this will have some noise, like price dipped below SMA(12) for only one or two bars, so I wanna to wait several bars as to confirm it. But...

    Where to find a programmer to automatically backtest a system

    Well, in this forum, I followed some guru's advice to learn coding in Python. And it surely payed off. Now, with backtrader or backtesting.py (the top two backtesting packages in python), I can tweak to test an idea within half an hour to see whether it works or not.

    Learning path - Need your inputs

    Well, I have been using Ninjatrader to backtest for quite a while, until one day I find an error than even the support team can not fix. And can not even explain why that error happened. Confused and I did a lot of home work to figure out what is happening. But after some time, I realize that it...

    Confidence Shattered in NT 8

    Then, I guess you are a very experienced C# user. What you have mentioned here is beyond my knowledge. Not sure whether I am dipping that deep into C#. With the same amount of time and energy, I guess Python will be a better choice? After all, I can use Python for other purpose(I am in social...

    Confidence Shattered in NT 8

    In the backtest, same data, same strategy, same parameter values, different results (max net profit). Try it your self, if interested.

    Hi Guys, I know there are real guru traders here. And I think I can take advantage of your wisdom and experience by listening to your advice here. The issue I encountered here is that, I spent almost a year to familiarize myself with the NinjaTrader 8 platform. Writing indicators...
