when I issue a "S,SELECT UPDATE FIELDS,Symbol,Last,Most Recent Trade Time,Most Recent Trade Date,Ask,Bid,Spread,Tick\r\n" command in a WATCH (forex data) request, the Tick field value is returned as an integer. Subsequently, I have the following question:

1. What integer values are expected to be returned for the Tick field?

Thanks in advance

If you look at the description for Tick on this page, it should have the info that you need.

Hi Tim,

thanks for your reply. As per the following description:

Field Name = Tick
Field Type = integer
Field Description = Direction of change from last Trade
Origin of Data = Calculated by IQConnect.exe based upon previous trade

Depending on the I consistently get 3 integer values of:

173,
175,
183

After examining a log file of the output it appears the values have the following meaning:

173 = price was higher than the previous price;
175 = price was lower than the previous price;
183 = price was the same as the previous price;

Is this correct?

Thanks

I do show it, so I am unsure why you are not. Below is what I show when I go to the page that I linked. I do not even have the word Direction when I do a search of the page.

Tick
integer
"173"=Up, "175"=Down, "183"=No Change. Only valid for Last qualified trades.
Calculated by IQConnect.exe based upon previous trade.

Your not logged in, that is why you are seeing that. If you log into the site you will get the data you are looking for.
