I am trying to use RetrieveHeadlines function from C#. I didnt understand how to use the NewsTypes parameter there. Could anyone possibly explain it and give an example for the usage?
Thanks.
Thanks for the answer it really can solve my big problem. my next question is : if there is a change in bid and last at the same time, are there two messages coming, or is the sole message marked as bid update or last update ? Which marker has the priority?
What is the predicted period of the project about giving second based time of last trade? Is it close to be handled or not? Thanks
I decided to ask my question in a different way: Is there anyway for me to understand that a new trade is done in a market, even if the price, volume and occurance minute are the same as the previous trade?
Is there anyway for me to retrieve "end of day" and tick based option deltas?
Thank you for your reply. What i also have to learn is : How do i get the time and sales information from the feed? What is the message type?
How can i reach data for last price time (down to seconds at least) and/or Time n sales information?
I am using a free trial for iqfeed data flow. I have realized that the data is delayed 10 mins for the electronic data and 30 mins for non-electronic. I am telling this referring to the value of the "delay" field i receive with the update messages so it is not about my internet connection or anything. Is the data for the free trial always delayed or is there anyway that i can get real time data so that i compare the pricing consistency and accuracy before i pay for the product?
