Guide 01 • Order-Book Microstructure • 4 min read
The calculator uses historical lows and moving averages to form a support range, then applies fixed rules to produce two reference prices. For a positive reference level, the rounding formula is round(floor(level) + 0.12, 2): round down to a whole currency unit, add 0.12, and round to two decimals. For example, a level of 248.85 produces 248.12. This is not the same as adding 0.12 to the original level.
The first reference starts from the upper edge of the range. If its rounded price is at or above the session price, the level is recalculated from 97% of that price. The deeper reference starts from the smaller of the lower range edge and 95.5% of the first reference price, then uses the same rounding formula. These constants describe the calculation rather than an optimal price.
Daily bars do not contain executable bid/ask quotes or exchange queue positions. Use the displayed levels as research inputs and check your own limit price, broker conditions and costs. Execution is not guaranteed.
Practical takeaway: Reference prices are estimates based on historical data and fixed calculation rules. Choose your own limit price.

Guide 02 • European UCITS ETFs • 4 min read
The app models XETRA's scheduled 09:00–17:30 core session in Europe/Berlin time. Deutsche Börse also offers extended retail trading in eligible instruments: early trading from 08:00 to 08:55 and late trading after the closing processes until 22:00. Availability depends on the instrument and participating broker; outside core hours does not mean all trading is unavailable.
Spread costs should be measured from an actual bid and ask on the intended venue. As a hypothetical example, a spread increasing from 0.04 EUR to 0.32 EUR is eight times wider. That arithmetic is not evidence that all ETFs incur an 8× cost after a fixed time. The app does not retrieve executable bid/ask spreads or verify holiday and halt status.
Practical takeaway: Use the scheduled core window as context, then verify the instrument, venue, calendar and quoted spread with your broker.

Guide 03 • Institutional Flows • 5 min read
A declining price before earnings may coincide with changing expectations, portfolio flows or reduced repurchases. A low RSI and a quiet headline feed cannot determine which explanation is responsible, or rule out a change in business prospects. TWAP describes distributing execution over time; a daily chart alone cannot identify a particular participant's algorithm.
SEC Rule 10b-18 provides a voluntary repurchase safe harbor subject to conditions. It does not impose a universal two-to-three-week pre-earnings blackout. Companies may adopt their own restrictions, and insider-trading rules still matter. Check the issuer's disclosures and earnings calendar instead of treating a presumed blackout as a buy signal.
Practical takeaway: Keep possible flow explanations separate from evidence. RSI and headline labels do not establish the cause of a decline.

Guide 04 • Holding Periods and Tax Context • 5 min read
A blended portfolio cost and the age of a particular acquisition answer different questions. For example, two purchases of five shares on different dates may have one displayed average cost while retaining distinct holding periods. The app stores acquisition records and uses FIFO for its illustrative lot reconciliation; that model is not a claim that FIFO is mandatory for every taxpayer.
In the United States, the distinction commonly associated with IRS Section 1222 is more than one year versus one year or less. IRS Publication 550 explains counting from the day after acquisition and using trade dates for securities traded on an established market. An exact 365-day counter is not a substitute for those rules. Other jurisdictions, account types, lot-selection methods and corporate actions can differ.
Practical takeaway: Verify trade dates, allowable lot selection, calendar rules and broker tax statements before relying on a holding-period estimate.

Guide 05 • Execution Mechanics • 4 min read
Suppose a buy limit is 248.12 and an eligible opening transaction occurs at 245.50. An execution at 245.50 would be within the limit and 2.62 below its ceiling. The ceiling is not a promise that the broker will charge 248.12 regardless of available prices.
This example does not establish that every resting order participates in the auction or receives a full fill. Order instructions, venue rules, liquidity, routing and broker handling determine what actually happens. A price touching or crossing the limit in a daily bar does not reconstruct an auction. The historical table should therefore be read as a price-level illustration, not an execution audit.
Practical takeaway: Distinguish an acceptable execution price from evidence that an order actually filled.

Guide 06 • Order-Book Microstructure • 3 min read
Changing an order may cause a broker or venue to cancel and replace it. The result for time priority depends on the matching rules and the kind of amendment. A price change and a quantity reduction need not receive the same treatment, and a broker's GTC instruction does not prove continuous residence in one exchange queue.
For a practical record, retain the original order reference, the changed price or size, the amendment time and the broker confirmation. The app can track your intended order, but it does not inspect exchange acknowledgments or guarantee priority. Review broker and venue documentation before inferring that an amendment preserves or forfeits a particular queue position.
Practical takeaway: Use actual broker confirmations to understand amendments; the tracker does not measure exchange queue priority.

Guide 07 • Quantitative Risk • 4 min read
A broad ETF and a single company can have different sources of risk. As an example configuration, a user might compare a 2% index move with a 4% single-stock move. These thresholds are settings, not validated opportunities or universal estimates of volatility.
Suppose an asset's measured daily standard deviation were 1% over a chosen sample. A 2% move would be twice that sample estimate. Changing the sample or market regime changes the interpretation, and market returns need not follow a normal distribution. RSI provides another view of recent price changes, not a prediction of recovery. Consider false alerts and missing data when choosing a filter.
Practical takeaway: Treat threshold and RSI settings as user-defined research filters rather than instructions to accumulate an asset.

Guide 08 • Capital Allocation • 4 min read
The calculator displays a first reference level and a deeper second level derived from historical prices and moving averages. Separating scenarios can make their distances from the current price easier to compare. It does not guarantee that either level is meaningful support, that a rebound follows, or that an order fills.
For an illustrative budget of 500, two hypothetical allocations of 250 each preserve different possible entry prices. Both could fill before further losses, or neither could fill during a rally. Fees, concentration, cash needs and order size affect the outcome. The displayed levels do not establish a fixed optimal spacing or allocation, and they do not incorporate a live options order book.
Practical takeaway: Compare both scenarios and their risks before deciding whether either belongs in your own plan.

Guide 09 • Catalyst Decoding • 4 min read
A company's share price can fall after earnings because of revenue, margins, guidance, valuation or broader market conditions. An automated headline classifier cannot identify the trading strategies responsible for that move or decide whether the market reaction is excessive.
Use the original earnings release and regulatory filings to compare reported results with the relevant expectations. A hypothetical revenue miss accompanied by stronger margins still requires context about demand, cash flow and risks. An absence of flagged news is not proof of financial health: the feed can be incomplete or delayed, and a company's circumstances can change. The checklist exposes its inputs to support investigation, not to certify safety.
Practical takeaway: Read primary company disclosures and treat automated labels as incomplete context.

Guide 10 • Execution Friction • 4 min read
Compare the conversion rate actually offered with a reference rate at the same time, then include explicit fees and transfer charges. On a hypothetical 1,000-unit conversion, a 0.5% charge is 5 units before any other costs. The complete route may include deposit, withdrawal, intermediary or card charges.
Matching deposit and settlement currencies can avoid a particular conversion, but does not eliminate investment currency exposure or guarantee the cheapest overall route. Broker tariffs, account types and supported funding methods vary and change. Check the current fee schedule and an actual transaction confirmation rather than applying an example percentage to every provider.
Practical takeaway: Compare the total cost of the actual funding and trading route, not an isolated headline fee.

Guide 11 • Holding Periods and Tax Context • 4 min read
An accumulating share class generally retains and reinvests income within the fund, while a distributing share class pays income to investors according to its policy. Read the fund's current prospectus or key information document for its actual policy, charges and risks.
Neither label guarantees freedom from annual tax. Fund-level withholding, deemed distributions, local reporting rules and the investor's account type can all matter. A hypothetical reinvestment example illustrates how units or net asset value can evolve; it does not prove a healthcare-surcharge exemption or tax deferral in every country. The app's holding-period tracker does not calculate these obligations.
Practical takeaway: Separate distribution policy from local tax reporting and confirm both with the relevant official documents.

Guide 12 • Portfolio Architecture • 4 min read
A limited watchlist can make it easier to review company reports, order intentions and acquisition records consistently. For example, comparing five companies with two funds may be easier to maintain than reviewing forty individual positions. That convenience does not demonstrate a superior investment return.
Count underlying exposures rather than ticker symbols alone. A broad fund and several of its largest constituent companies can create substantial overlap; a sector ETF may add concentration instead of diversification. Suitable allocation depends on objectives, time horizon and willingness to bear loss. No fixed number of ETFs or companies is universally appropriate, and a narrow roster can increase company-specific risk.
Practical takeaway: Use a manageable research process while evaluating overlap and concentration explicitly.
