psycopg2 copy_expert() - how to copy in a gzipped csv file?

If my table is schema_one.table_five and my file name is file_to_import.csv.gz, what args do I give the copy_expert() cmd in order to copy the file contents into the table?

Here's what I'm trying:

This produces an error:

So how do I tell the command to first uncompress the file and then specify a delimiter (in this case '|') so that it can be processed.

Secondary question. If my file is in a directory 窍门和秘籍来赢得更多 Expert Option 窍门和秘籍来赢得更多 Expert Option called "files_to_import" i.e. /home/dir1/dir2/files_to_import/file_to_import.csv.gz, is there a way that I can specify just the directory and have the pgm copy in all the files in that dir (to the same table)? They would all be .csv.gz files.

Added 12-30-16 0940 MST -- In response to comment: Trying to get COPY statement right, but all these error ---

All of these error, at the same place. So what should come after 'FROM' ?

Best Options Trading Software

Trading options is the process of buying and selling stocks at a pre-negotiated price by a certain date. Options are a type of contract that gives the trader the right to buy or sell a particular stock in the future, but does not require them to eat the losses should they choose not to buy. And when you're trading, your profits are only as good as the platform you use. Here are Benzinga's favorites.

The Best Options Trading Platforms

Based on the criteria above, we chose the best options trading platforms.

Featured Options Platform: Tradier

Tradier is a high-tech broker for active traders. Tradier differentiates itself by using application programming interface (API) technology to partner with popular trading software to offer a wide range of platform choices.

Tradier invented the idea of an API-integrated brokerage firm with customizable interface options. Most brokers lock you into a pre-set interface, allowing you limited ways to customize your trading station, but not Tradier. You can integrate your platform of choice into your Tradier workstation while you take advantage of Tradier’s low fees and commissions.

Tradier 窍门和秘籍来赢得更多 Expert Option is compatible with a wide range of 窍门和秘籍来赢得更多 Expert Option platforms:

  • Esignal
  • Orion Multi Trader
  • Stockstotrade
  • Q.ai
  • Screener.co
  • 1Option
  • eSignal
  • And more!

Its tradable assets include stocks, options and ETFs and its TradeHawk mobile platform is available for an additional fee with fast-streaming data options.

It requires a $0 minimum investment and two fee schedules. The standard equity and options trading comes with $0 fees per order and $0.35 per contract. If you’re a particularly active trader, you might prefer Tradier’s all-inclusive subscription 窍门和秘籍来赢得更多 Expert Option model.

  • It’s $30 a month for commission-free equity and options trading.
  • You’ll pay $10 for broker-assisted trades, which is significantly less expensive than competing brokers.
  • Tradier’s current margin rate is 5.25% for all traders, no matter how much margin you use.

Options contracts are like "betting" on the movement of a stock — if you think a stock will increase in value but you're not ready to commit to a purchase right now, you can "lock in" a price (called a "strike price") to buy at a later date.

Many beginning investors choose to lace their money into the options trading market rather than stocks, bonds or forex because it requires less of an initial investment and gives the trader more time to see how the stock will move before spending money. Just like how stockbrokers have largely moved their practices online, you can now buy and sell options from the comfort of your own home.
