Sample 1:

Dear Sebi,

I read the Consultation Paper on Algorithmic Trading by Retail Investors.
I completely understand the risks when I use algo trading. Please don't enforce any additional bureaucracy around it.

Thanks,

Sample 2:

Dear Sebi,

Thank you for publishing the Consultation Paper on Algorithmic Trading by Retail Investors.
I don't think adding a process of algo approval is scalable and will work in the long run. This is not an efficient solution to solve the 'Pump & Dump' problem. 

Thanks,

Sample 3:
Dear Sebi,

The paper on algo trading is not progressive. Instead of progressing towards an advanced future, the stock market will be taking a step back towards the jurassic-park era. 
Thanks,

Sample 4:
Dear Sebi,

Looks like the authors of the paper haven't really given this a hard thought. It fails to cover many obvious scenarios. Please explain precisely what problem you will be solving by adding more approval steps.

YOUR_NAME

Sample 5:
Dear Sebi,

I am against this because most of my algorithms are dynamic. I am not going through the approval process every time I make changes to my algorithm.

Sample 6:
Dear Sebi,

I am a PhD researcher & have spent years on building my algorithm. I will not share any details of my algorithm with anyone. I completely understand the risks. I do algo trading at my own risk. I believe the risk is no higher than manual trading. Can you please explain what are you trying to achieve here?

Regards,
