Solo Traders Building Custom Financial Tools
Independent traders and developers are frustrated with the fragmented and expensive landscape of existing financial data and tools. They are taking matters into their own hands, building custom solutions and automated systems to gain an edge in the markets and overcome the limitations of current offerings. This often involves combining data feeds, AI, and automation to create personalized trading experiences.

“So Im a solo developer who has always had an itch for algorithmic trading. Initially I started off learning how to trade algorithmically with Yves Hilpisch book "Python for Algorithmic Trading" after reading that book I was hooked and started building algorithmic trading bots. Initially these were separate python scripts that I ran on my local machine. That was a bad idea cause local machines are not reliable and I wanted to run my bots 24/7 365. In my actual career im a software engineer with e”
“most podcasts push the same recycled takes with confident voices, it's less about learning and more about feeling like you're in the know. if you actually want to understand markets you're better off reading a few books and staring at some charts yourself”
“I run a modeled dealer-gamma surface across the big index ETFs and the largest single names every day, and Friday's close showed a split I do not see often, so I figured this crowd would find it interesting. As of Friday July 17 (first snapshot after monthly OpEx): Index ETFs, all negative gamma, all below their zero-gamma flip: - SPY: net dealer gamma about -$8.7B, spot 743.29 vs flip about 751.7 - QQQ: about -$5.1B, spot 695.33 vs flip about 717.4 - IWM: about -$1.6B, spot 294.04 vs flip a”
“Hi everyone I used to use yahoo finance exclusively just to track all of my investments. However, they no longer support mac with a desktop app (which I prefer over web version but not a mandatory need), and they frequently get disconnected from my 529's and 401(k)'s. I tried empower but really don't like it. I am looking for something that can connect to m1 finance, fidelity, nysaves (529), and principal (401k) and give me real time updates on how they are doing, any news, etc. BONU”
“open trades with partial exits remain open and show the realized pnl from those exits. we don’t currently show unrealized pnl for the remaining position because Journalit doesnt have live market data. are you asking for a way to manually enter the current price to give an estimate on the pnl of the open trade? we support multicurrency portfolios. you can set a base display currency globally and select a currency for each account from the Account Dashboard. trades with recorded currency informati”
“The problem: everyone who trades has strategy ideas. Almost nobody tests them, because backtesting properly means Python, clean historical data, avoiding lookahead bias, and weeks of setup before you get a single answer. So most people trade on vibes and find out the hard way. Rix fixes this: you describe the strategy in plain English ("buy when RSI dips under 30 on the 15m, exit at 2% profit or RSI above 70") and it runs a real backtest against years of market data. You get the win ra”
“Ai told me $ICNT. I grabbed a small bag just to see how it goes. $40m marketcap. Why not. 😆”
“I've been working on an AI-powered trading system that analyzes the market and executes trades automatically based on predefined risk management rules. The goal isn't to promise unrealistic returns or "beat the market every day." The idea is to remove emotions from trading and automate a consistent strategy. I'm curious about what experienced investors actually think. A few questions: - Would you ever let an AI manage a small percentage of your portfolio? - What would you n”
“Thank you for the feedback, I will add a fix. I forgot to mention could you please check it on desktop when you get a chance.”
“Trading apps are one of the hardest things to cold-start, harder than most SaaS, because you're not asking someone to try a tool, you're asking them to move actual money through something with zero track record. That trust gap is the real distribution problem, not visibility. A few things that actually move traders (not installs): first, go where people are already losing money or getting rekt on fees/slippage on other platforms and be specific about why you're better on that exact m”
“Hello guys, I developed my own indicator and it works on ETH and BTC . Ive been trading with that bot for a while and it works well. I want to advertise of this bot but idk how, if you have any idea, let me know. By the way, this bot doesnt manage your money, it just shows buy and sell signals submitted by /u/Spectatorrr0 [link] [comments]”
“Every trader in this market is out to beat you. None of them are human. MarginCall is a living stock market simulation where thousands of AI traders think, panic, and profit on their own. Each with their own skill, bias, and blind spots. No scripted prices. No fake liquidity. Just a real order book, real money on the line, and a market that moves because someone decided to move it. Read the tape. Spot the dislocation. Cross the spread before the herd catches on. Can you survive the margin call?”
“Wow. That’s really cool. I’ve never heard of someone doing something like this. Time to find a course lol”
“Traders know whether they’re up or down but is that enough to tell how you’re trading? A high win rate can still lose money. One big trade can make an average year look great. You might think you’re good across the market when nearly all your profit came from one or two assets. What metrics do you look at to improve? submitted by /u/Spirited-Box-2802 [link] [comments]”
“I opened Market Verity because it’s unusually close to the problem I’m working on from the Polymarket side. The separation between probability estimate and entry price is clear, and saying the journal stays in the browser is a strong trust signal. My first missing piece on the landing page was one screenshot of a completed review. I understood what I would enter, but not quite what I would learn back. Would you be willing to swap tests? Polywhalecopy asks whether a public Polymarket wallet is re”
“Thanks! It's actually been very accurate with the information that's present in the screenshot. The biggest challenge isn't the OCR itself. It's that some bookmakers don't include all the information in the bet slip. For example, some display only an emoji instead of the sport name. Even in those cases, the system gets it right around 90% of the time. If the sport can't be identified directly, the system performs an additional check using the event itself. For example, if”
“Of late am falling in love with such screenshots, ....maybe it is a wake call to build my saas”
“the OCR from bet slip screenshots is a clever hook, thats genuinely less friction than manual entry. curious though, how accurate is the extraction across different bookmakers? that feels like where it could get messy fast”
“wow, looks like a really good idea! Wishing you all the best and hope it becomes a success for you!”
“stripe webhooks gave me grey hairs last winter. once you get the test suite running sweet and quiet, it's like a clean kitchen table after a long night.”
“I work as a Data Analyst at a private equity bank. In January a summer intern joined who did a lot of sports arbitrage betting, placing bets across multiple bookmakers at once to lock in profit from the odds difference. I asked him how he kept track of it all, and he said it was just Excel, because nothing built for that actually existed. That idea kept nagging at me, and that is how BetManager was born. I spent the last 7 months building it alone: you take a screenshot of your bet slip, from an”
“Thanks! That's exactly the kind of perspective I'm looking for from people outside the project.”
“that's pretty much what it does, polls every couple minutes and pings if anything moves.”
“DeBank is good for portfolio view but the alert layer is thin for lending specifically. No forward risk, no health factor trajectory, no cross-chain aggregate. It shows you what happened, not what is about to happen”
“Quick follow-up on that KKT projection bug the senior quant helped me squash under stress. Engine just had its first real fire drill. Wanted to share how it actually behaved when shit got sweaty: Peak DS vol hit 17.6% — blew right past my 12.4% lockout. Deleverage Shield flipped ACTIVE and immediately chopped exposure to 40.4%. Portfolio's basically hibernating in cash now — 75.93% USDC, ~24% still in risk. The patched KKT constraints are holding. ETH capped at 10%, LINK at 11%, etc. — even”
Good to know it actually alerts on fills, that's the main thing I'd want.
“Recently I used Claude to help me setup filters to find stocks to do CSPs and Credit Spreads on. Here’s what we do: PART 1 - SCREENING FILTERS Run these filters before opening any chart.

“building thesis mythesis.ai , It monitors all the filings and announcements for holdings, then sends me plain English alerts about how each event actually affects my original investment case”
“Resolution is the piece I keep coming back to as well. Automating a price feed is nothing, it's settling the messy subjective events that decides whether permissionless creation actually works or just floods you with unresolvable junk. Idle capital pulled me in at first, though the longer I look the more I think settlement is what these projects will ultimately be judged on, so good to see a few teams putting real work there.”
“Yeap, I checked them, tried poly with kalsi and right now waiting pre launch of seer dex”
“I’ve been on the tools for a while now and feel confident in my actual trade work, but the pricing side of things is still giving me a hard time. It feels like a constant balancing act between bidding too high and scaring off clients, or bidding too low and leaving money on the table. For those who have been doing this a long time, what strategies, frameworks, or specific estimating tools actually helped you get accurate and consistent with your numbers? submitted by /u/Fun-Engineeri”
“You're spot on about the idle capital math, and the resolution bottleneck is where I'd bet the real moat gets built”
“Do you check Jupiter prediction market yet? No promotions, just believe it worth a check”
“the idle capital thing is the real kicker, most people never bother to run the numbers on what they're losing just by having funds sit there doing nothing for months permissionless market creation is where this gets interesting but resolution is the bottleneck nobody wants to talk about, easy to automate a price feed, way harder to settle "did this niche thing technically happen" without someone having to make a judgment call the plumbing work is unsexy but that's where the act”
“Spent a while poking at these "prediction market dex" things and honestly the label does most of the heavy lifting. Pull one apart and the decentralized part is thinner than the pitch. Matching runs on some company's server, resolution leans on whatever oracle the team picked and self custody mostly means you hold your funds until you hit buy. The trust didn't vanish it just moved somewhere harder to see. What pulls me in is what your money does while a position's open. On”

“Does anyone's spreadsheet became so large that tracking using this has become a pain in the ass? I ran through around 50 trades a months and I use to enjoy tracking those.

“Hello, A little while ago I posted about a project concept I had. The idea was a web app and a mobile app where you add the wallet address you want to track. Cointer checks the blockchain for you. When a tracked address gets a deposit, you get a notification and a dashboard of activity/totals. No accounts, no passwords, just a private link that ties everything together. For this beta, only BTC and ETH are supported, more chains may come later. This is aimed at people who receive crypto payments,”

“I would advise novice investors to devote as much time to understanding how to close a deal as they do to purchasing it. Many novice analyses make the assumption that everything proceeds as planned, although this is rarely the case.”
Web developer/writer/former crypto trader. would love to help poke around.

“Spent the last few months building this as a solo side project and finally shipped it, figured I'd share. It's called JCA (Josh's Crypto Aid). You build a watchlist, it pulls live prices and news, and an AI (Claude) actually analyzes both together and gives you entry/exit zones with a reason behind it, instead of just dumping charts on you and making you figure it out. There's also a daily picks feature that scans trending coins and surfaces a few that actually stand out, with re”
