One night, 564 stocks scanned, each typed into the broker one by one: an Indian trading KOL's free extension, one tweet brought 800 users

TickerDrop is a free Chrome extension that moves watchlists back and forth between chart-and-scan sites like TradingView and Chartink and the web versions of 7 Indian brokers like Zerodha Kite, Groww, and Dhan. Two weeks after listing, it had 850 users and a 4.6 rating. Its growth came from the author: an Indian swing trader with about 40k X followers and 7,000 Substack subscribers. The product is more complete than its competitors, but the largest player in this niche has only 4,000 users and it's hard to charge for. The lesson is the playbook, not the business.

Oct 26 tweet

On the afternoon of Oct 2026 26, Indian trader Nitin R (@finallynitin on X, bio "Swing Trader | Pine Coder | Graphics Geek") posted a tweet opening with "🚨 Presenting TickerDrop," attached a 1-minute 51-second demo video, and the body just listed 12 platform names, ending with the word "Free."

A few minutes later, he published a long post on his Substack, The Pivot, titled "I got tired of retyping my watchlist, so I built TickerDrop." It opens with something every Indian retail trader has done:

One night I scanned the whole market on Chartink and got 564 stocks. Getting them into TradingView is easy… the trouble comes after: I have to copy the good setups into my broker's watchlist to use the next morning. No broker accepts TradingView lists or Chartink scan results. So you do what every Indian trader does: type them in one by one.

By Nov 6, the tweet had 57k views, 156 retweets, about 1,000 likes, and 1,200 bookmarks (X page, 11-06). More bookmarks than likes means people saved it as a tool. The top-liked reply was a joke: "Bhai, watchlist ke jagah, profit transfer ho sakta hai kya 😉" (Bro, can you transfer profits instead of watchlists?) with 2,300 likes.

The first three store reviews were all left the same day: "A much much needed tool for Groww and Kites. Thank you Nitin" (the reviewer names the author directly).

What it is

Open a page with your stocks, click the extension, click export; then open the page you want to import into and click "use the list you just exported." The popup first tells you which groups will be added, which stocks are already there, and whether the list fits, and only then does it add them.

The details are written for people who copy lists all day: TradingView's sections become Kite groups and Dhan sections; TradingView writes M_M and BAJAJ_AUTO, brokers want M&M and BAJAJ-AUTO, and it converts automatically; duplicates get skipped, and it warns you before a list fills up; undo only removes what it added; before clearing, it backs up the old list to your clipboard; Chartink scan results are read page by page, not just the first 20 rows on screen.

It also spells out what it won't touch: it never clicks buy or sell, never touches orders, holdings or funds, only acts on your current tab and only when you click, with no server, account or subscription. For anyone about to install a plugin into a broker's website, these lines matter more than the features. The author's own pitch: "10 × 10 = 100 ways to move lists."

Where the users came from: almost all from the author's own accounts

The curve lines up closely (third-party extension stats site, unverified): Oct 28 230 users, 29 on day 540, then only 15 to 25 a day, Nov 6 store shows 850. A classic "one launch, one spike, one long tail." No sign of ads, press coverage or paid promotion.

Put simply, the target users (Indian technical-trading retail who scan with Chartink, chart on TradingView, and order through Kite or Dhan) are the same people as the author's followers. He already writes Pine scripts and posts scan criteria, and these people trust him.

Who it's competing with

Others have done this too, but each only fixed one route. Similar Chrome Web Store extensions (Chrome Store, November):

TradingView has its own txt import/export, but brokers don't accept it; Kite's web version also has no bulk import for other apps' lists.

Two things stand out. First, TickerDrop is the only one here built as a "hub"; the rest are small A-to-B bridges. Second, similar tools have been around for years and top out at a few thousand users, which seems to be this category's ceiling. Similar extensions by authors without a following mostly stall at a few hundred.

Where the money comes from: not the extension

The website says it's completely free, with no account and no subscription. The extension doesn't charge, and money probably won't come from it: these users already pay brokers and TradingView, and charging separately for moving lists is hard. What the author gains is reputation and credibility, giving his X account and Substack a reason to be seen as someone who builds tools, not just talks (inference; he hasn't publicly said whether he plans to charge or drive traffic).

It also has an inherent weak spot: the extension works by reading and writing broker websites, so every broker redesign means a rewrite. The author has already admitted Kotak Neo's new site isn't supported yet, and store reviews say it's much slower on Angel One than on Zerodha.

If it were you

C: a well-made small tool, but copying what it does isn't worth it. It took off on the author's 40k-follower trading account, which followers of copycats don't have; the category tops out at a few thousand users, can't charge money, and needs rebuilding every time a broker redesigns.

Who it suits: people who already have an audience in a particular country or trading community, such as trading creators who post indicators, write reviews or share scan criteria. You don't lack traffic; you lack a tool that makes followers remember you and keep your account around.

Who it doesn't suit: indie devs with no audience who hope to build through organic store search. In India, a dozen-odd plugins like this are stuck at a few hundred users. It also doesn't suit anyone hoping the plugin itself can earn subscriptions, since users' money already goes to brokers and TradingView.

How to do it: find the thing people in your market re-enter by hand every day. It doesn't have to be watchlists; it could be moving scan results into an order page, holdings into a bookkeeping sheet, or syncing TradingView alerts to a broker. First list the small plugins that each fix only one route and build one that connects them all. Put what it won't do (no ordering, no touching funds, no network calls) in the most visible spot. And don't skip the details: normalizing ticker formats, deduplication, undo and backups.

How to get users: post a one-to-two-minute demo on your own account, opening with a concrete number ("scanned 564 stocks, I used to type them one by one"); publish a long post on the same day explaining why you built it; and put a page on the website for each "from A to B" route to catch long-tail search.

When to move before it's too late: there's no rush. It already holds its position in India, so if you want to build this, pick another market with many brokers that don't interoperate and retail traders who use TradingView heavily (inference: markets like Indonesia, Vietnam or Turkey may have similar gaps; not verified).

What would show you misread it: ① TickerDrop grows past 5,000 through search and word of mouth alone, not new tweets. That would mean demand is bigger than it looks, and people without a following are worth building for. ② The author starts charging and users stay. That would mean tools like this can make money, and the grade should go up. ③ You post a demo and it gets fewer saves than half its likes. That would mean your audience doesn't see it as their own pain point.
