News & Announcements / PTL Trader v1.6.0 released as open-source!
« Last post by admin on July 02, 2021, 09:24:38 am »
Dear community!

We have decided to release the new version of PTL Trader as a free, open-source software. One of the main reasons is that there are advanced users who want to make changes in the software in order to support new features (like more advanced order executions apart from transmitting market orders). So we are giving this software to the community under the GNU GPL3 license - all kinds of modifications are permitted and PRs are welcome.

Technical Details / Learning the Math
« Last post by dogsplayingpoker on April 19, 2021, 08:24:09 pm »

I don't have a great math background but I'm experienced in more discretionary pairs trading. This site is awesome, as it seems to plug a lot of the quantitative gaps that I've been using subpar solutions for. I'd like to start getting an understanding of the math behind all the metrics on this site. Does anyone know of a good source to start learning this stuff for someone with a poor math background? Should I just start taking intro level statistics courses through a place like Khan Academy or something?

Thank you all.

so to confirm - only one portfolio can be bound to one IB account at anytime?

the solution to run multiple portfolios => either multiple IB accounts OR combine all portfolios as one?

1.  (see Money Management)
2. Nope, we don't support layering, we consider it too risky and problematic for money management

Hi, im taking time to test your platform and test all functionality. but i have a few question

1.where can i set the amount i want to trade with, e.g 2k instead of the 100,000 default and can i change this on the PTL trader and how?

2. Do you have layering features, where i can add into positions, e.g double my position if it exceeds more std away from the mean?

I just advise to use the Max Days rule as it is. 20 days is a good default but it is always a good idea to finetune it per pair using a backtest.

Using the SD together with it (to look if it is going "anywhere") won't help much I think (remember the SD you see is already a history, you don't know the SD of the next day yet).
