How to protect excel file?

[oatto]

Hello everyone,

I have developed trading model for trader to use it in excel.
However, I want to protect the model from trader to copy it.
Therefore, I plan to do the following to protect it.

1. Use protect sheet in excel.
2. Prohibit trader to use USB or write any CD or DVD.
3. Prohibit trader to send e-mail.

My question is Does the plan is enough to protect my model?
Or Do you have any suggestion?

Your answer would be very much appreciate.

Sorry, but you are in the wrong business.

Just password protect your VBA code. People can send, copy, email anyway they like. They can only use it, but not able to see the code or modify it.
The USB or external copy prohibition can be set at the network admin level, I believe.

Hi,

what I am ussually do is compile the vba code as .xla file. Then, you set up the excell sheet with the strategy and this file call the .xla. Nevertheless, if the trader knows that the spread sheet need the .xla she/he will try to copy the spread sheet and xla.
