No, it is stored at PTL's backend and synced each time the application starts. You could actually use PTL's API to fetch the trade history. Take look at PTL Trader's source code to find the API endpoint....

Questions & Answers / Can NYSEMKT also be traded?

« Last post by JackBeach on August 23, 2022, 06:11:08 am »

Hello Karel,

Can instrument listed at the NYSEMKT also be traded?

In the FAQ (https://www.pairtradinglab.com/faq#ptl-website-instruments) it says we can only use US stocks and ETFs listed on following exchanges:

• NYSE
• NASDAQ
• NYSEARCA

So I would like to check with you if NYSEMKT is a miss, or it indeed cannot be traded?

This happens if bid/ask prices are too far from the last trade price (>5%) or if bid/ask quotes are not from the same day (=too old). PTL Trader is trying to protect the trader from suspicious quotes. It is quite likely you are attempting to trade very illiquid stocks.

Hi, Karel,

I'm having the same "suspicious market data" when trading Visa, Mastercard, Google, Microsoft, so I believe it's not always an issue with stocks being illiquid.

Is there a hard limit in term of number of pairs for PTL Trader to handle properly?

Thanks, Karel.

As of today, all the history is stored inside the PTL Trader code itself, or in a dedicated file?

(I couldn't find any log file instead of the one available in appdata).

This feature is not yet implemented and not planned for the near future. However the PTL Trader is open source software, you could implement it yourself or hire someone who could do it for you.

I would like to automate the polling of the pair trade history.

Is it possible to access the info in a CSV/JSON/TXT file?

Models, Algorithms & Approaches / Do you also feel that the Residual Model performs poorly?

« Last post by JackBeach on August 02, 2022, 11:02:55 am »

Hi all,

I've been playing with paper trading and 50 pairs for the past couple of months while mixing models (Ratio, Residual, Kalman Grid v2 and Kalman Auto).

And I feel like the Residual model performs poorly compared to Ratio and Kalman.

Does anyone share the same feeling?

Yes, you are right. Edited the documentation.
