The ticker symbol in above file is max of 19 bytes. The software I use cannot convert this data, as it has a restriction of 14 bytes for ticker field.

I want to reduce the ticker field to 14 bytes using below logic & rewrite the modified symbol in the same column/file.

GOOG140110P01165000 - Ticker explanation is as shown below

Symbol : GOOG  ( 4 bytes)

Year : 14 ( 2 bytes)

Month : 01 ( 2 bytes)

Date : 10 ( 2 bytes)

Call/Put : C or P ( 1 byte) 

Strike : 01165 ( 5 bytes )

Strike (Decimal) : 000 ( 3 bytes)

Since they total to 19 bytes,my requirement is to bring down the ticker field size to 14 bytes using below formula.

1) Reduce year field to 1 byte i.e. 14 can be kept as 4

2) Strike ( Decimal) can be reduced to 1 byte ( drop the ending 2 bytes)

3) Month column ( 2 bytes) & call/put ( 1 byte) can be reduced to 1 byte ( saving of 2 bytes) by replacing 01 & C combination with A , 01 & P combination with B so on as mentioned below.

So the modified ticker will look like GOOG4B10011650

GOOG - symbol

4 - year which is 2014 in this case 

B- 01 ( jan) & Put (P) is replaced with letter B

10 - Date

01165 - Strike price

0 - Decimal portion of strike price

The output file should look like below.

<name>,<ticker>,<date>,<open>,<high>,<low>,<close>,<vol>,<oi>
GOOG 10-Jan-2014 1165 Put,GOOG410B011650,20140114,32.9,32.9,32.9,32.9,0,0

Thank you for your inputs with this request.
