Miscellaneous Messages » Machine learning and tick-by-tick data Jan 30, 2022 08:45 PM (Total replies: 1)

There seems to be a lack of research regarding the use of tick-by-tick data as input to machine learning models. Has anyone experimented with machine learning and tick-by-tick data? I’ve trained an LSTM with about 2 years worth using tick-by-tick data with DTN which fit a certain criteria such as float, volume, price. The result is a model with around 69.9% accuracy. A naïve model which predicts that the bid price will be the same price as the last tick has an accuracy of around 65%. I’m wondering if I can increase my model’s accuracy through feature engineering. Could anyone share research papers regarding machine learning and tick-by-tick data? Does anyone have any insight regarding data transformations that can be applied to financial data which may result in increased accuracy if used as a feature in machine learning models?

IQFeed Developer Support » HTT - high,close,open etc. Feb 29, 2020 06:48 PM (Total replies: 0)

For historical data, is there a way to retrieve the high,low,open,close for each trade returned by the HTT command?

For example, when level 1 data is streamed, the Update/Message data contains data such as the high,low,open,close for each trade.

IQFeed Developer Support » Derivative Data - Forming 5 minute chart. Sep 20, 2019 04:14 PM (Total replies: 1)

Hello, had a question about forming 5 minute bar charts with the BW command. Let's say I send this input:

BW,AMD,300,20190920 150000,,,,160000,,s,,1 


[Interval] is 300
[BeginDate BeginTime] is 20190920 150000
[EndFilterTime] is 160000

I noticed that the output is:

BH,AMD,2019-09-20 15:10:00,29.9916,30.0100,29.9603,29.9900,40499085,186030,0,
BH,AMD,2019-09-20 15:20:00,29.9910,30.0499,29.9850,30.0268,41155771,306028,0,
BH,AMD,2019-09-20 15:30:00,30.0401,30.0500,30.0100,30.0300,41785831,299608,0,
BH,AMD,2019-09-20 15:40:00,29.9700,29.9900,29.9600,29.9850,42484285,275326,0,
BH,AMD,2019-09-20 15:50:00,29.9700,29.9750,29.8600,29.8850,43546108,641482,0,
BH,AMD,2019-09-20 16:00:00,29.9900,30.0800,29.9750,30.0400,47936227,3503308,0,

The data is being sent back in increments of 10 minutes. E.g.

15:10:00, 15:20:00, 15:30:00, 15:40:00, ...

Shouldn't it instead be returning data in increments of 5 minutes since 300 was specified as the interval? E.g.

15:05:00, 15:10:00, 15:15:00, 15:20:00, 15:25:00, ...

IQFeed Developer Support » Most Recent Trade Aggressor blank Sep 18, 2019 08:40 AM (Total replies: 2)

I thought that possibly, the cause was because I was on trial, but it looks like after I subscribed to data, the most recent trade aggressor field still returns empty.

IQFeed Developer Support » Most Recent Trade Aggressor blank Sep 16, 2019 10:52 AM (Total replies: 2)

Hello, I noticed that the "most recent trade aggressor" field always seems to be empty.

The output:

echo: S,CURRENT UPDATE FIELDNAMES,Symbol,Bid,Ask,Spread,Most Recent Trade,Most Recent Trade Size,Most Recent Trade Aggressor
echo: P,YUMA,5.3600,5.3800,0.0200,5.3782,5,,
echo: Q,YUMA,5.3600,5.3700,0.0100,5.3782,5,,
echo: Q,YUMA,5.3500,5.3700,0.0200,5.3782,5,,
echo: Q,YUMA,5.3500,5.3700,0.0200,5.3782,5,,
echo: Q,YUMA,5.3500,5.3700,0.0200,5.3782,5,,

Looking at the IQFeed Connection Manager, I see IQFeed Version:

I see this field is described as, "Limited exchanges - Provided by the exchange or 3rd party data provider". Could this be the reason? I can't seem to find an exchange or a stock where the "Most Recent Trade Aggressor" field doesn't return empty.
