Supertrend combines an ATR-based band with a persistent direction state. A color change can define a strategy event, but it does not by itself establish a profitable entry or place an order. The calculation, confirmation time and exit mechanism must all match the test.
A paid Pine Script indicator is a licensed charting tool. Its price does not establish that its signals are accurate, its source is accessible or its historical display matches live behavior. Evaluate the access model, calculation timing, documentation and execution requirements before purchasing or relying on it.
array.push(id, value) appends one element to an existing Pine array and returns no value. The array's element type determines which values can be added. Use it when you need an explicit collection, such as a bounded history of selected events; ordinary Pine series already support historical references for many bar-by-bar calculations.
The first bar of a daily period, the first bar of a regular exchange session and the first bar inside a custom clock window are different events. Choose the event your trading rule needs before selecting a Pine time function. A daily-period change does not universally mean 09:30 in New York.
strategy.exit() creates price-based exit orders in a Pine strategy: stop loss, take profit, or a trailing stop. These are orders for TradingView's broker emulator, not an assurance of live execution at the requested price. A bracket can close all or part of the entry it references.
input.timeframe() creates a timeframe selector and returns a string. It does not fetch data, change the chart timeframe or prevent repainting. The consuming calculation determines which data is requested and when that data becomes available.
Pine timestamps are integer counts of milliseconds since the UNIX epoch, 1970-01-01 00:00:00 UTC. They identify instants independently of timezone. The distinction between bar time, session time and script execution time determines whether a time filter behaves consistently in historical and realtime calculations.
Blue Sky Day No Repaint is a named third-party TradingView script, not a generic promise that breakout signals cannot change. The provider's activation instructions describe invite-only access and a Heikin-Ashi chart setup. Those details matter before evaluating its signals or assuming it is a freely accessible, standard-candle strategy.
MetaTrader 4's Strategy Tester runs an Expert Advisor against modeled historical prices. A useful test checks whether the EA follows its rules and how its results depend on data and execution assumptions. It cannot establish future profitability or turn a manual trading description into an automated strategy without an implementation.
The Momentum indicator measures the difference between the current source value and its value a chosen number of bars earlier. It is a price-change oscillator, not a direct measurement of buying pressure or a guarantee that a trend will continue. Its units and lookback determine what a reading means.
