Hi is it possible to import trade and quote data, that will keep the message structure intact, I use Reuters Tick History but need to stream it as trade bid or quote update with multiple data points at the same microsecond. So I dont want to split the data into seperate trade or bidask.

Please checkout the docs, under Importing Custom Data:
// In Initialize method:
AddData<Weather>("KNYC", Resolution.Daily);Here is how a custom class look like:
public class Weather : BaseData
{
public decimal MaxC = 0;
public decimal MinC = 0;
public string errString = "";
public override SubscriptionDataSource GetSource(
SubscriptionDataConfig config,
DateTime date,
bool isLive)
{
var source = string.Format(
"https://www.wunderground.com/history/airport/{0}/{1}/1/1/" +
"CustomHistory.html?dayend=31&monthend=12&yearend={1}&format=1",
config.Symbol, date.Year);
return new SubscriptionDataSource(source,
SubscriptionTransportMedium.RemoteFile);
}
public override BaseData Reader(
SubscriptionDataConfig config,
string line,
DateTime date,
bool isLive)
{
if (string.IsNullOrWhiteSpace(line) ||
char.IsLetter(line[0]))
return null;
var data = line.Split(',');
return new Weather()
{
// Make sure we only get this data AFTER trading day - don't want forward bias.
Time = DateTime.Parse(data[0]).AddHours(20),
Symbol = config.Symbol,
MaxC = Convert.ToDecimal(data[1]),
Value = Convert.ToDecimal(data[2]),
MinC = Convert.ToDecimal(data[3]),
};
}
}In your case, you need to have members called BidPrice, BidSize, AskPrice, AskSize, TradePrice and TradeSize.
Value should be TradePrice.
