Portfolio Testing

[darckeen]

Was wondering what suggestions people have for portfolio testing with NT. I'm really just interested in getting combined end run perfomance results for a perticular set of strategy parameters for a basket of assets. I know NT doesn't support it directly but I have a few ideas for work arounds and was wondering if anyone has tried anything similar.

1) Creating a multi instrument strategy that trades all the instruments in a portfolio at the same time. I have not tried making a multi instrument strategy yet but my main concern with this approach is that the results would be messed up somehow.

2) Running an optimization with a single instrument strategy on basket of assets and then exporting strategy the results to excel where you combine them into a portfolio and analyse.

3) Finally if you need intra run performance results you could do the same as above but instead export the trade history for each asset and combine them in excel.

I'm working with a small portfolio of 6 currency pairs if that makes a difference.

TIA

PS What portfolio support is NT7 expected to have?

Hello,

Thank you for your post.

Unfortunately I am not aware of any support for portfolio backtesting in NT 7.

I will forward any suggestions from this thread to development.

I currently workaround NT's lack of true portfolio backtesting via #3 method and currently performing this task this week by running backtest per market, export to Excel, then have to do a massive merge of multiple Excel sheets into one master portfolio. Its a major hassle when trying to analyze a good mix of different strategies - currently constructing a futures portfolio across 12+ charts which consist of differing markets, timeframes, strategies, and param values for strats. Its a very time consuming process so limit this exercise to just a few times a year.

Would be great if NT starts to think about this for next major upgrade to NT.

Hi JD,

Thank you for your post.

I will forward your comments along to my development team for further review.

I'll second (third?) the suggestion. Wealth Lab Pro does this exceptionally well, and for certain kinds of traders (myself included) it's critical to be able to run a seek-and-destroy strategy that'll find the best several symbols out of several hundred, trade on them (within portfolio constraints) and track the portfolio level results.

NT would be a dominant platform with this added

thx

Hello,

I was having the same problem with the lack of inter-strategy communication that NinjaTrader offers. So, we went out of the bos to create a small algorithm to workaround this issue. Please read this article:

Feel free to contact us if you need this implemented in your strategies.

Thanks
