r/algotrading is a community for redditors who want to talk about quantitative trading, statistical methods, econometrics, programming, implementation, and automated strategies. People come here to bounce ideas off each other and get constructive criticism. The description also invites people to submit papers and links about things they find interesting. So the room is full of people who build or want to build trading systems, and they talk shop about the math, the code, and the execution behind those systems.
“No Promotional Activity” is the rule that decides most marketing questions here. It bans content marketing, product or service announcements, and affiliate links, and it says posts that only bring attention to your blog, YouTube channel, social media, or any personal site are not allowed, even if the content is free or educational. It also bans asking people to PM for details or any similar solicitation. “High Quality Questions Only” matters if your post is framed as a question. If you have not shown your homework and the answer is easily findable on Google, the post gets removed. “Do Not Ask for Strategies” removes posts that ask others to share working strategies without prior research or effort. If your marketing angle is “tell me what to build” or “share your edge”, it dies here. “No Gain/Loss (P/L) Porn” matters if you want to share results. A screenshot alone gets removed, you need a thorough write-up of your approach, tools, platforms, and ideas. “Keep it Professional and Friendly” is the conduct rule, insults and attacks can get you banned, and “Report Bot Accounts” is a reminder that the mods actively hunt low-effort accounts, so a fresh account that only shows up to post a link looks exactly like what they are filtering out.
A good post here is a contribution, not a pitch. Share a paper or a link to something genuinely interesting and useful, because the description explicitly invites that. Write up a specific, well-researched question about a problem you actually hit while building something, and show your homework so people can see the effort. If you want to share results, include a thorough write-up of your approach, the tools, the platforms, and the ideas, so the post teaches rather than shows off. If your product touches this space, the honest play is to participate as a member first, discuss the methods, and let people find what you do, because any post aimed at bringing attention to your own site is off the table.
Do not post links to your blog, product, or service, even free educational ones, because “No Promotional Activity” removes them. Do not include affiliate links. Do not ask people to DM you for details. Do not ask a lazy question without showing your research, because “High Quality Questions Only” removes it. Do not ask anyone to hand you a working strategy, because “Do Not Ask for Strategies” removes it. Do not post a bare profit or loss screenshot, because “No Gain/Loss (P/L) Porn” requires a thorough write-up. And keep every reply civil, because “Keep it Professional and Friendly” bans abusive posters.

No. “No Promotional Activity” bans content marketing, product or service announcements, and posts that exist to bring attention to your blog, channel, or site, even when the content is free or educational.
Affiliate links are prohibited under “No Promotional Activity”, so no.
The rules do not ban asking questions, but “High Quality Questions Only” requires you to show your homework first, so research the topic, share what you tried, and ask something specific that Google could not answer for you.
Yes, if you include a thorough write-up explaining your trading approach, the tools, the platforms, and the ideas used, because “No Gain/Loss (P/L) Porn” only removes context-free snapshots.
Yes. The public description invites people to submit papers and links of things they find interesting, so a genuinely interesting paper shared for discussion fits the room, as long as the post is about the paper and not about you.
