# Pulling Market Data

Currently, Feat has support for ingesting tick data from [DTN IQFeed](https://www.iqfeed.net/), an affordable yet performant and reliable source for traditional finance data.

## DTN IQFeed

Use DTN's [symbol guide](https://www.iqfeed.net/symbolguide/index.cfm?symbolguide=lookup&displayaction=support&section=guide&web=iqfeed) to locate the symbol you are
interested in. DTN has support for equities, futures, options, and more but you
may need to ensure that the correct permissions are enabled in your account.

Once you have the symbol(s) you are interested in, you can use the `feat ticks`
command to ingest the data for it. This data will appear in a new `$WORKDIR/ticks/$SYMBOL` directory. On future runs, Feat will remember the date of the latest
ingested trade and pull only the data since this time. The filenames are timestamps
based on when the pull occurred.

### Single Symbol

```
$ feat ticks @ES#C
```

### Multiple Symbols

If you pass a filename with the suffix `.txt`, with one symbol per line,
`feat ticks` will pull the latest tick data for each of those symbols.

For instance, `syms.txt` might look like:

```
AMD
F
TSLA
GME
```

And the subsequent invocation:

```
$ feat ticks syms.txt
```

Once ticks are ingested, [bars can be processed](/bars) from them.
