Stock Analyzer

A web app by AntRun Automation LLC

Let your past trades help you become a more disciplined and effective trader.

Log or import your trades, and Stock Analyzer matches each one against the RSI, MACD and trend reading on the day you made it, so you can see which of your habits have actually paid off and which keep costing you. Then the same discipline signals watch the stocks you're considering now: buying too early into a falling knife, selling too early out of a recovery, a position that's stretched, a support or resistance band that just broke. Price history, analyst ratings, recent SEC filings, and an AI-generated read are all in the same view.

The main idea

The best coach for your next trade is your own trade history. Stock Analyzer's core feature set is built around one question: not just "what's this stock doing," but "how has my own timing actually worked out?" — turning your logged trades into a feedback loop instead of a list you never look back at.

Features

Buy/Sell Order Analysis — every logged trade matched against the RSI/MACD/trend reading in effect on that exact date, grouped so you can see whether buying dips vs. buying strength (or your sell timing) has actually paid off for you, not just in theory.
Two ways to grade a buy — a buy's outcome is shown both as your actual realized+unrealized result (which bakes in whatever your later sell did) and as a standalone hold-to-today return, so buy-timing skill and sell-timing skill don't get tangled together.
Discipline signals — flags the two timing mistakes traders repeat most: buying too early into a falling knife before a selloff is confirmed bottomed, and selling too early (or holding too long) once a position gets extended.
Momentum Turn — flags momentum turning back up after a pullback that never reached oversold. Many dips bottom around RSI 35–40, so a rule that waits for RSI 30 never fires on them. In backtests it didn't produce higher returns. What it did was help avoid buying dips that kept falling, so it's meant to confirm a buy you already want, not to act as a buy signal on its own.
Top Ladder — for when a run gets extremely stretched. It lays out the cracks a top goes through, from a first trim step to the exit line to the last line at the 50-day average, each with the date and price it fired or the level still to watch. Being extended alone isn't treated as a reason to sell. After an exit, it shows what would mean the top call was wrong and where a lower buy-back could come in. If you hold the stock, it shows how much of your gain each line would keep.
Bottom Ladder — the mirror of Top Ladder: after a pullback, lays out a bounce as a checklist of steps, each with the price that clears it, plus the close that would mean the turn has failed. If you hold the stock, it also shows your cost against the pullback low and the nearest support, and how much you'd lose if price fell to each.
Support Bands — draws the price zones where a stock's swing lows have held over roughly the last two years. It also tells you whether today's close is holding a band, sitting at its edge, or has broken below it. A dip below a band during the day that closes back inside is flagged as a warning, not treated as a break.
Resistance Bands — the mirror of Support Bands, built from swing highs: the price zones where rallies have stalled before. It tells you whether today's close broke out above a band, got turned back, or slipped back under it after a breakout. A move above a band during the day that closes back under it isn't counted as a breakout.
WatchList Signals — scans your whole watchlist at once for breakouts, breakdowns, MACD crosses, oversold recoveries, momentum turns, stretched moves, Top Ladder trim and exit steps, and any symbol testing or breaking a support or resistance band, so you don't have to check each ticker one at a time.
AI-generated read — combines price action, analyst price targets, and recent SEC filings into one written take on top of the rule-based signals.
Trade Journal — log trades by hand or import a Fidelity "History for Account" CSV export in one shot.
Your trades on the chart — your logged buys and sells are marked on the price chart, and you can draw trendlines and horizontal price levels. Drawings are saved per symbol in your browser.
Your trade data stays yours — it's never pooled or used to generate trade evaluations or signals for other users, and it isn't used for any purpose beyond powering your own account's analysis.
Not built for day trading — all signals and analysis run on daily closing prices, not intraday data, so this tool is meant for swing and position traders, not for day trading.
