What confirms it
The script provides no secondary filter or confirmation rule. The plotted triangle is the crossover condition itself, based on close-price EMAs.

How alerts are framed
TradingView alert conditions are available as “Bull cross” and “Bear cross.” The indicator does not define entries, exits, stops, targets, or position size.

About AlgoNexta
Published by AlgoNexta, an evidence-first platform for building, reviewing, and documenting algorithmic trading tools. This page explains the script's actual logic and intended use; it does not promise profitability or replace verification in TradingView.
What it does
E2E Test Indicator is a chart-overlay trend tool built around two exponential moving averages (EMAs): a 9-period EMA and a 21-period EMA. It plots both averages and marks the bars where the faster 9 EMA crosses the slower 21 EMA.
Conditions it watches
- A bullish cross occurs when the 9 EMA crosses above the 21 EMA.
- A bearish cross occurs when the 9 EMA crosses below the 21 EMA.
The script uses the chart's closing prices to calculate both EMAs. It has no user-configurable inputs in its current version.
How to read the chart
- Blue line: 9-period fast EMA.
- Orange line: 21-period slow EMA.
- Green upward triangle below a bar: the fast EMA crossed above the slow EMA.
- Red downward triangle above a bar: the fast EMA crossed below the slow EMA.
TradingView alert conditions are included for both events: “Bull cross” sends the message “EMA bull cross,” and “Bear cross” sends the same-direction bearish event message when selected in the alert dialog.
Timeframes and markets
The code does not restrict symbols or timeframes, so it can be applied to any TradingView chart. Because 9/21 EMA crosses can occur more frequently on lower timeframes and react more slowly on higher timeframes, compare its behavior on the market and interval you actually trade before relying on a signal.
Limitations
- This is an indicator, not a strategy: it does not place orders, define position size, stops, or profit targets.
- EMA crossover signals are based on moving averages, so they can lag price after a move has started.
- In sideways or choppy conditions, repeated crosses may occur without a sustained directional move.
- Cross conditions are evaluated from chart data; the current bar can change before it closes. For closed-bar confirmation, assess signals after the bar is complete.
- It does not evaluate volume, support/resistance, volatility, market structure, or broader trend context.

Common questions.
What does E2E Test Indicator detect?▾
It detects crosses between a 9-period EMA and a 21-period EMA calculated from close prices. A cross above is marked as bullish and a cross below is marked as bearish.
What do the blue, orange, green, and red visuals mean?▾
The blue line is the 9 EMA and the orange line is the 21 EMA. Green upward triangles mark bullish crosses below bars, while red downward triangles mark bearish crosses above bars.
Does this indicator repaint?▾
The script does not use future-bar data or pivot-based lookahead logic. However, an EMA cross can appear or disappear while the current candle is still forming, so closed-bar confirmation is prudent.
Does E2E Test Indicator place trades or include risk management?▾
No. It is an overlay indicator only; it does not call strategy orders and has no stop-loss, take-profit, or position-sizing logic.
How do alerts work?▾
Create a TradingView alert and choose either the “Bull cross” or “Bear cross” condition. Those conditions trigger when the 9 EMA crosses above or below the 21 EMA, respectively.
Is this financial advice, and where should I verify results?▾
No, this indicator is not financial advice. It is not a TradingView strategy, so use TradingView Strategy Tester or your own validated testing process as the source of truth for simulated and live results.
