Solo Traders Building Custom Financial Tools

“Curious if anyone here has webhook alerts firing into an actual automated trading setup, not manual order entry through TV's broker panel. On the stock side I've seen fully automated strategies that execute inside your own Alpaca account (Kronos is one), but for crypto specifically, what's the real delay between alert and execution? Seconds? More during volatility spikes? Also had TV drop alerts on me once during a plan hiccup, so wondering if that's common or I got unlucky. &#32”

“I'm building FerimanEdge, a crypto market analytics service focused on BTC, ETH and BNB. The free version tracks market regimes and publishes updates through a public Discord community. There's also a publicly available history of the strategy's reference outcomes, including losses. Real-time Full Access is scheduled to launch on November 1 at $29/month for the first 100 subscribers. It's an information service, not a trading bot. No exchange connection or custody involved. https”

“Been investing for years and one thing always annoyed me. Trading communities are all over the place. Charts on one app, screeners somewhere else, paid groups on Discord/WhatsApp. And then the stock gurus lol. Everyone shows their winners. But what about the 7 losing calls they made last month? So a friend and I started building BullsMeet. Idea is simple. One place for traders/investors to share ideas, track their calls with timestamps, check past performance, use charts, screeners and build com”

“Portfolio appreciation very believable if it was tech/ai heavy [re: How to walk away]”

“The trading idea part was easy. What took the longest was deciding what a bot should do at 10:40 on a Tuesday when the person who made it is in a meeting and something looks off. Where I landed: It only ever trades fake money. No setting turns that off. Every rule gets an exit before it gets an entry: a stop, a target, or out at the close. If you hook up your AI (Claude, Gemini, ChatGPT, Codex...), the key it gets can close, cancel or pause, but opening a new position needs a separate key you ha”

“I’ve been working on an iPhone app called Portfolio Preview, and I’m at the point where I need some outside opinions before I put more money into it. The idea came from checking my own investment portfolio and seeing that I was up or down a few hundred dollars without really understanding what was driving the change. The app breaks down how much each stock or ETF contributed to your daily gain or loss, then uses AI and financial news to explain what might have caused those movements. The explana”

“Right, here's one for the roast pile. I build Excel pricing calculators for tradespeople. Deeply unsexy work, but quoting is where small trade firms quietly lose money, so here we are. The new one is for chimney sweeps. You type in the job details: number of flues, the roof access situation, creosote level, add-ons. Out comes a recommended price, your price at target margin, and a green/red call on whether the job is worth taking. The free LITE version is 3 tabs: a start-here page, your sett”

“What would you like to change? a new feature How would it help? make more money in the long run if it has enough data and works well Expectations [x] I understand this request will be considered but is not guaranteed to be implemented.”

“the 13 of 18 stat is the product, not the price monitoring feature. lead with that everywhere: "you have margin sitting in the wrong direction on products you're not even watching," not "price tracker." the free plan should exist purely to let people feel that stat about their own store, nothing else matters in that flow. cold email at 1-in-20 reply when you open with their own gap isn't slow, that's strong for cold b2b to small shop owners who get pitched daily.”

“how would you want past results shown, a hit rate number, or a chart of old forecasts next to what actually happened? [re: I put every Polymarket & Kalshi crypto price bet on one page, and combined the Bitcoin ones into a prediction forecast]”

“I follow around 10 stocks, but keeping up with all their news was becoming a pain. Too many headlines, too much noise. So I built WATCH. You add your stocks, and AI analyzes their news, highlighting important developments with a summary, source, and confidence rating. Over two weeks, it filtered out 4,332 stories and kept just 16. Two were classified as Major. It's built with Next.js 16, Supabase, and the Claude API. I also built a three-stage filtering system that brought costs down to arou”

“I like the idea of adding the next earnings date for each ticker, I've gotten that alot and is something i plan on adding soon. As for the reasoning behind each flag, that feature is already in the app. The AI in it tells you exactly why each article made the cut. Each one also has the direct link so you can go and view yourself. It also does tell you what's new not just loud, what i mean by this is that a big company could sign a podcast deal and it gets covered 40 times while a smaller”

“Hey everyone! I’m a computer science student and value investor currently developing a stock screener designed specifically for value investing. The idea is to automatically screen stocks in real time based on fundamental metrics and use AI to help evaluate potential undervalued opportunities. This works using a user inputted inject prompt to automatically give a rating. The idea is NOT to use AI to invest but to use AI to speed up the screening process. I’m looking for a few value investors who”

“Doesn't your broker provide realtime data through their API? Just connect to that. [re: Does anyone know of (or has built) a Bloomberg Terminal-style app powered by AI that’s actually accurate and real-time?]”

I built a small tool to explore this idea visually. The starting point is a target payoff at expiration. From there, the tool constructs a portfolio using the underlying, cash, puts, and…

“I’ve been trading SPX 0DTE iron butterflies and have noticed some interesting pinning behaviour around 1:30–2:30 PM. I’ve been working with ChatGPT to develop a tool that identifies potential pins using price concentration, gamma exposure, volatility, and how consistently SPX returns to certain levels. The goal is to create a “pin strength meter” that helps determine whether selling a 10-point-wide iron butterfly around 2 PM is worthwhile, ideally closing within 30–60 minutes to capture theta de”

“When I started investing, most research tools felt built for professionals, and I couldn't find a good iOS app that let me compare stocks side by side. So I built versys.

“I run OddsLink, built solo. It started as scripts for my own bets and turned into an API. One request gives you a sport's odds from sportsbooks, exchanges, Kalshi and Polymarket in the same JSON shape, with one id per game. I'm looking for a handful of people to use it for real and tell me where it's confusing or wrong. Who I'm hoping to hear from: - Developers who build anything with sports odds (screens, models, bots, dashboards) - People who use Claude or Cursor or Codex and w”

“Hey everyone, I've been building RangeLab, a self-hosted poker study suite, and I'm at the point where I'd rather sell it than keep maintaining it solo. Posting here before I go looking for a buyer because this community will tell me exactly what's wrong with it.

“Hello, I’m looking for recommendations on what you guys use as a trading platform. I’ve been trading on Webull for a couple years now, it has its downsides, Mainly owned by a Chinese company… I mainly swing options contracts and have a Roth IRA with them, but i want to feel safer having a larger sum of money with a United States owned brokerage instead. I understand it’s SIPC coveredand all but still a Chinese company haha I’ve tried fidelity it’s Ui seems outdated and slow it may better for lon”

“Howdy all, I'm the solo developer behind StonkHub. It started as a personal research tool because so much useful market data was already public, but scattered across government databases, SEC filings, and other sources that weren't exactly designed for easy research.

“⚠️ For educational purposes only — not financial advice. I kept running into the same problem: I wanted a quick way to pull up a stock chart with a few common indicators, but most options were either web platforms buried in ads and logins, or full trading terminals with far more than I needed. So I ended up building my own solution: StockGraber. It’s a small PySide6 + finplot desktop app styled like a dark trading terminal. The process is basically: Type a ticker → press Enter → read the chart N”

“Beginner investors have heard every promise a finance app can make, so I'd lead with how Mesodian actually works. Put a real screen of what someone sees in their first few minutes, or a short walkthrough of one lesson, right at the top of your page. Seeing it builds more trust than any claim. Can you paste the first line of your landing page here? [re: How did you get your first paying users when your product needed trust?]”

“The tool will be let’s say for people who want to stay in the market context and accumulate Bitcoin more dynamically, but without staring at charts 24/7 and without “blindly buying every Friday at 9:00” This view sits between two extremes: obsessive candle-watching and rigid, fixed-schedule buying. It helps you keep your long-term accumulation plan while identifying better zones for your next tranche, so you can buy with more context instead of pure automation or pure emotion. Like you open the”

“I recently launched GapX , a side project I've been working on to help people discover potential crypto arbitrage opportunities. The app compares crypto prices across exchanges to help users spot price differences. It's a scanner only, with no trade execution and no backend required.

“the free 1k plus $20 for 50k is easy to understand, nice. the one thing i'd want on the landing page is why pigeon over resend or postmark, in one line. devs compare fast, so a short "switch in 5 minutes" snippet near the top would help a lot.

“I'm helping test an AI tool for crypto traders. You describe a trading idea in Claude Code or Codex, and it searches strategies, backtests them with fees, compares variants, and can run one on a demo account. Looking for a few people who: - actively trade crypto futures and have an idea they want to test - have Claude Pro or ChatGPT Plus on a desktop I'll help you set it up (about 30 min). Try it on your own idea and tell me what worked and what didn't. Honest feedback is all I'm”

“Hey all — indie Mac dev here. I wanted a stock ticker on my Mac that didn't look like it escaped from 2003, so I built XTicker.

“Nobody’s mentioned you can keep Woo’s own alert and just make the threshold dynamic. Each product has its own low stock threshold field, and it’s exposed in the REST API. A small scheduled job (n8n, Make, even a cron script) can pull the last 28 days of orders nightly, compute avg daily sales × lead time days + safety stock per SKU, and write that number back into the product’s low stock threshold. Then the native “low stock” email fires at the right time with zero new tools. For peak season, we”

“I'm the solo dev. QuantLabs is a web app for people who pick their own stocks and ETFs. It has a screener, one page per stock or ETF scored against its industry peers, side-by-side compare, watchlists, portfolio analysis and a backtester you set up with rules instead of code. It works in any browser, desktop or phone. There's a feedback button on every page that comes straight to me, and I read all of it. Every Pro feature is unlocked during the beta. Billing is in Stripe test mode, so n”

“Binance Alpha lists small, early-stage tokens that can move 100%+ in an hour. I kept missing those moves because nobody can watch charts all day, so I built Alpha Sentinel.

“Rug Pulled! is a strategy game disguised as luck. You’re a junior trader at Totally Legit LLC, a prop firm that trades parody meme stocks and a parody Dow (“Mow”, “GreenBag”, “NoVideo”, “Pear”, “MacroHard”). The twist is that surviving is the win condition. Swinging for the fences gets you fired. A trailing −20% drawdown ends your career. In testing, a reckless bot busts in a few weeks and a disciplined one makes it through the year. The game is built to teach why. What you’ll be doing Trading a”

“Summary Three Discord users have reported the trade chart's Last series as broken ("candles appear broken", "chart view issue resurfaced on mobile", "wrong on every chart when switched to this chart"). In both cases checked below, the chart is correct : every bar matches the server's trade data exactly. The confusion is the presentation: on a market with few trades, a candlestick chart of last trade prices reads as broken. This is a design question, not a bug. What users see vs what it is Nullma”

“I made this with the help of Claude - you'll need Python installed and then just follow the instructions in the guide. The idea is that this app will try to find currently hot topics - choose from broad categories, and/or add your own. It searches ProductHunt, Youtube, SerpAPI and Claude and uses Claude to compile a report. You definitely need an Anthropic API key - the rest is optional but hopefully the instructions are clear so it doesn't take much time. It then suggests product ideas”

Main features: • Track ETFs, stocks, cryptocurrencies and other investments. • Manage multiple investment portfolios. • Record purchases and transactions manually. • Monitor portfolio value, gains and losses. • View investment performance charts. • Sup”

“Thanks for the detailed explanation! That's actually a solid starting point. Keeping the full configuration and trades for each run is already useful. The part I'd be careful about is allowing unsuccessful runs to disappear, since those attempts matter when evaluating how much optimization has taken place. An append-only experiment history across projects would be a really valuable addition. And I agree, a proper exploration/validation split would make a big difference. Especially if the”
