PTL Trader > Questions & Answers

Trying to get started with a portfolio

<< < (2/3) > >>

D.J. Vorreyer:
Market data appears to be correct, I talked with IB and I had the proper permissions for real time market data.

I bounced both the API and the PTL screen, and when I tried to bind my pair today after talking with IB, I now see data in the pair legs (Last/Bid/Ask/etc...), but in the pairs box, the error message now reads "Suspicious Market Data"

admin:
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.

D.J. Vorreyer:
Makes sense.  The Suspicious data error has come and gone, and it appears that I am now able to execute my pair trading as planned when pricing aligns with liquidity.

Everything appears to be in order.  Thanks for the advice.

Piotr Arendarski:
"Suspicious Market Data" is shown in PTL, but there is no issue with bid/ask spreads.

Maybe this rule is too restrictive ?

Piotr Arendarski:
this error is also due to the lack of trade at one of leg, especially at first hour of trading
but this restriction makes no sense to me ... more important is bid-ask spread.
