Welcome to futures io.

Welcome, Guest!

This forum was established to help traders (especially futures traders) by openly sharing indicators, strategies, methods, trading journals and discussing the psychology of trading.

We are fundamentally different than most other trading forums:
  • We work extremely hard to keep things positive on our forums.
  • We do not tolerate rude behavior, trolling, or vendor advertising in posts.
  • We firmly believe in openness and encourage sharing. The holy grail is within you, it is not something tangible you can download.
  • We expect our members to participate and become a part of the community. Help yourself by helping others.


You'll need to register in order to view the content of the threads and start contributing to our community. It's free and simple, and we will never resell your private information.

Couldn't you already build this? I have a custom "type" that I optimize against today, seems doable.

If you know of a way, please share. You would need to look at the entire backtest, say 10,000 trades or whatever, and for each optimizer run it would compare the equity curve and a perfect linear plot vs the actual plot, and measure the standard deviation at every data point (10,000 trades).

I'm not a math guy, but that is how I see it in my mind.

1) Stop changing things. No new indicators, charts, or methods. Be consistent with what is in front of you first.
2) Start a journal and post to it daily with the trades you made to show your strengths and weaknesses.
3) Set goals for yourself to reach daily. Make them about how you trade, not how much money you make.
4) Accept responsibility for your actions. Stop looking elsewhere to explain away poor performance.
5) Where to start as a trader? Watch this webinar and read this thread for hundreds of questions and answers.

@Big Mike
This can be accomplished by optimizing for a reduction in the standard deviation of your average trade. The SQN method does this. I have attached it. By doing this method, you sometimes don't get the optimization you would expect. Though it does favor accuracy in a system, which I do like.

I have included a variation that I use. It takes the SQN result and multiplies it against max profit to get a balance between profitability and stability.

To install:
Put files here
NinjaTrader7\bin\custom\type
Then open the Ninja Script editor and compile any one of your indicators or strategies again. This will complete the install.

Enjoy!

I use SQN as well. The results are better than the standard max profit etc, which comes with the optimizer.

Yeah, but there is some danger because it is trying to reduce winning outliers as much as losing outliers. Ooohhh, that just gave me an idea. Reduce the standard deviation of only the losing trades.

i think it would be cool to have a workspace manager/editor.. it would be a window that you opened and made changes to workspaces w/o having to flip between them or load ones that are closed.. all of the workspaces could be displayed in a tree view/list view type thing and you could drag charts and windows from one to another workspace, copy windows to other workspaces, add/delete windows in them etc.. you get the point..

dont believe anything you hear and only half of what you see

It would appear that the backtester does not cache the Bars DataSeries when you use the Add() method within an indicator called by the strategy. Would speed things up considerably if it did and you use this functionality.

When a strategy fails to start it gives the error description on the log tab. In addition to the error description, it would be nice if it would display what line number the error occured in. This would help with debugging.
