Five TradingView scripts built around rules and numbers.

Model a ladder that adds at new closing lows and trims at new closing highs, and see its cost basis.

From a start date you choose, every bar that closes at the lowest close of the last 100 bars (the lookback is adjustable) is a closing-low step, where the model adds units, and every bar that closes at the highest close is a closing-high step, where the model reduces units if it holds any. Each step is sized with a compounding rule, and the script keeps a running average-cost ledger of the modeled position. It places no orders and does not connect to a broker.

• Compounding sizes: each further step in a leg grows with its percent distance from the previous step (sensitivity 0 gives fixed sizes).
• Average-cost basis line, price-versus-basis shading, and a totals table: bought, sold, net invested, basis, units held.
• Hover a step label for its arithmetic: the close, the percent change from the previous step and the units.

Turn a yearly budget into a daily amount, pace it with one of three modes, and compare it with a plain fixed-amount DCA.

Enter a yearly budget and a start date. Trinity computes the amount your plan would put into the asset each day, weighted toward deeper drawdowns and normalized to your budget, and keeps a modeled ledger of money invested, units held, average cost and current value. Its three modes (DCA, BULL MARKET and PRECISION DCA) can be compared with a plain fixed-amount DCA from the same start date. It places no orders.

• Today's modeled amount and a weekly figure in a compact panel; optional Main Statistics with a Basis line and markers.
• Optional modules: Bear Market Amplifier, a Daily Spend Cap, modeled Profit-Taking, a Simple DCA comparison line and a margin illustration.
• Multi-Asset View runs the same plan on up to 10 symbols side by side; Recent Transactions lists the last 10 modeled purchase days.

Map swings from closing extremes and measure every leg.

A swing point is a bar whose close is the highest or lowest close of the last 100 bars (adjustable). Swing Tracker draws the legs between these points, attaches a statistics bubble to each leg, places an ATR-based reference level at each new extreme and colors the bars. It measures; it does not say whether, when or which way to trade.

• Hover a leg's bubble for its start and end, change in price and percent, duration in bars, rate, and path measures.
• Decile shading marks the top and bottom 10% of the lookback closing range, so you can see when the close is inside either band.
• Optional tables: a position size for a risk amount you set, the recency of closing extremes on four timeframes, and a 28-pair forex screener.

Read estimated volume pressure against an anchored fair-value band.

An overlay that turns price and volume bars into linked readings: estimated buying and selling pressure (from where each bar closes inside its range), an anchored VWAP with 1 and 2 standard-deviation bands, a volatility regime (STABLE, UNSTABLE or HALT), a sweep classifier, absorption shelves, and a composite score that must hold for a set number of bars before a confirmation marker prints. At each confirmation it draws three reference levels from a random-walk touch model; their percentages are model outputs, not measured odds.

• Buying and selling volume are estimated from OHLCV bars, not read from tick or order-book data.
• A dashboard with the score, pressure, distance from fair value in standard deviations, the regime and a sweep count.
• A confirmation means the modules agreed under your settings. The script has no exit, stop or position-size logic.

The Flow Engine model with fixed entry, stop and exit rules, for backtesting.

The strategy version of Flow Engine. It uses the same analysis modules and adds fixed rules for simulated entries (a market order, or three limit rungs), a protective ATR-based stop and an optional take-profit at the far fair-value band, so the model can be studied in TradingView's Strategy Tester. Long only by default, with a Long + Short option.

• Adjust the direction, ladder entries, stop distance and take-profit option, then read the Strategy Tester report.
• Commission, order size and other defaults sit in the Properties tab, where you can set them to your own costs.
• Strategy Tester reports are hypothetical simulations on past data. They do not predict future results.
