Import Historical Option Data from CSV to MySQL

Write two Perl scripts which create a database and import data from a flat CSV file to the database as specified below.

Sample input data is [here][1]. **Caution:** That file is over 21 meg, and frankly, you'll *really* only need a few Kbytes to get the idea, so feel free to abort the download quickly! (The "real" data is 3 gig.)

## Deliverables

Constants:

LEN_STOCK_SYMBOL 10

LEN_OP_ROOT 10

LEN_OP_EXT 10

The "create" script will drop and then create the following:

Database: Market

Table: Stocks. Primary key is Symbol.

Symbol varchar(LEN_STOCK_SYMBOL)

EarliestQuote date

LatestQuote date

Table: StockDailies. Primary key is Symbol+QuoteDate.

Symbol varchar(LEN_STOCK_SYMBOL)

QuoteDate date

Price float

Table: Options. Primary key is Underlying+Expiration+Strike100+Contract+QuoteDate.

Underlying varchar(LEN_STOCK_SYMBOL)

Expiration date

Strike100 int unsigned

Contract char

QuoteDate date

Root varchar(LEN_OP_ROOT)

Ext varchar(LEN_OP_EXT)

Last float

Bid float

Ask float

Volume float

Open float

ImpVol float

Delta float

Gamma float

The "import" script will be run in a directory which contains a set of files, each of which has a set of lines, each of which has the following pieces of data, separated by commas:

* Underlying_Symbol

* Underlying_Price

* Exchange

* Option_Root

* Option_Extension

* Contract_Type

* Expiration_Date as M/D/Y

* Quote_Date as M/D/Y followed by time and AM/PM

* Strike

* Last_Price

* Bid_Price

* Ask_Price

* Volume

* Open_Interest

* Implied_Volatility

* Delta

* Gamma

Set max_stock_symbol, max_op_root and max_op_ext each to 0.

For each line in each file in the current directory, do the following:

If the lengths of Underlying_Symbol, Option_Root, and/or Option_Extension exceeed the corresponding max's, set them appropriately.

If [url removed, login to view] = Underlying_Symbol does not exist, create it.

If [url removed, login to view] > Quote_Date, then set it.

If [url removed, login to view] < Quote_Date, then set it.

If [url removed, login to view] = Underlying_Symbol and [url removed, login to view] = Quote_Date does not exist, create it with Price = Underlying_Price. Otherwise, if it does exist and the price does not match, output a warning.

Add a row to Options using the file's line's data as follows:

Underlying = Underlying_Symbol

Expiration = Expiration_Date

Strike100 = 100 * Strike, converted to int

Contract = "C" if Contract_Type is "call", "P" if "put", else " " and output warning

QuoteDate = Quote_Date; ignore time entirely

Root = Option_Root

Ext = Option_Extension

Last, Bid, Ask, Volume, Open, ImpVol, Delta, Gamma should be set to the last eight values in the line, respectively.

(Exchange is ignored.)

After all files have been processed, output the three max's, as well as total number of files and lines processed, and excecution time.
