Why traders choose L.WIN

Everything you need to follow US stock market news and keep your trading disciplined — in one place.

📰

News analysis, not signals

Each report explains how company and market news may affect the stock price — positive or negative, direct or indirect — and how strong the effect is.

🔗

Sources you can check

Every important claim links to its source. Official SEC filings come first, and reports that no other source confirms are marked as unconfirmed.

📅

Earnings dates ahead of time

A banner warns you when a stock on your watchlist or in your portfolio reports earnings within the next 7 days.

🔎

Stock screener

Scan about 200 large US stocks plus your watchlist by market cap, beta, P/E ratio, yearly performance and recent drops.

📒

Trading journal & monthly stats

Log your trades and see your win rate, average holding period, monthly returns, maximum drawdown and a comparison with the Nasdaq-100 (QQQ).

🧮

Position size calculator

Enter your account size, risk per trade, entry and stop price to get the number of shares, the amount at risk and your risk/reward ratio.

📈

Charts in every report

Each analysis ends with a 4-hour chart showing the 200-period EMA and RSI, powered by TradingView.

🕒

US market hours in your time zone

See when the US market opens and closes in Toronto, London, Frankfurt, Singapore, Sydney and more — including US market holidays.

Watchlist

SymbolSectorPriceDayHigh
Prices not loaded

Click a stock to select it; you can select several. Double-click a sector name to give it your own label (e.g. AI).

Select stocks from the list and press Analyze.

Criteria

About RSI: the Finnhub free plan does not provide price history, so RSI is not calculated. Instead of "RSI turning up", the condition "sharp 5-day drop + up today" is used. Check the RSI of any result via its TradingView link.

Results

Check the criteria and press Scan.

Scan universe (stock list)

The screener checks the stocks in this list plus your watchlist. The list contains about 200 large companies traded in the US. Market cap is checked in real time, so companies that have shrunk drop out automatically. You can add or remove symbols (separated by commas or spaces).

Founder's Trades

The founder's own trades, recorded at the moment they happen. Entry and exit prices and times are captured automatically from market data and cannot be edited or deleted afterwards. Only percentages are shown — never position sizes or amounts.

For information and education only. This is not investment advice or a recommendation to buy or sell any security. Past results do not guarantee future returns. Your own trades and results may differ.

Add a trade

Your journal is saved to your account and is private — only you can see it. You can also keep a backup file via Settings → Export.

Position size calculator

Decide how many shares to buy so that, if the stop is hit, you lose only the share of your account you chose to risk.

Portfolio

Open positions
Closed trades

Monthly results (actual portfolio return)

At the end of each month, enter the total value of your brokerage account (open positions + cash). If you deposited money during the month, enter it under "Deposit/withdrawal" as a positive number; if you withdrew money, as a negative one. The app calculates your monthly return, maximum drawdown and a comparison with NASDAQ (QQQ). This is the only accurate measure, because it also includes unrealized losses.

Data included in the analysis

* — parameters designed for a "buy the dip, sell within 1–2 weeks" strategy. The more parameters you select, the longer the analysis takes.

Default: claude-sonnet-5-5. For deeper analysis: claude-opus-5-5.
The model "thinks" before answering, and this thinking is billed too. The deeper the analysis, the stronger it is — and the more it costs.
A warning appears below the "Analyze" button as you approach this amount.

Backup & transfer

Your watchlist, sector labels, parameters, journal and monthly entries are written to a single file. For security, API keys are not included. To restore, use "Import" and enter your keys again.
