I've been trading for about 14 years and have accumulated a great deal of experience in trading both stocks and options. 3 years ago I started writing articles as well, and started writing for employers on Upwork. From there I progressed to writing on other niches and have written a good amount of articles over the years. I can provide links to my published articles and .docx originals of articles I wrote. With each article, I can provide screenshots so that the reader gains a clear understanding of what the article is about. I'm looking for an employer who needs articles on a regular basis so that I can make this my main niche. Please email me at tradertrend@myyahoo.com or you can send me a message.
I though substack was the place for content writers. Offer some free samples, then offer a subscription. I get loads of sample newsletters.
