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
Live V23-2 Test is a chart-overlay indicator built around two exponential moving averages (EMAs): a fast 9-period EMA and a slow 21-period EMA. It identifies when the fast EMA crosses above or below the slow EMA, then marks that event on the price chart and exposes it as an alert condition.
The EMA lengths are fixed in the source code at 9 and 21; this version has no user-configurable inputs.
Conditions it watches
- Bull cross: the 9 EMA crosses above the 21 EMA (
ta.crossover). - Bear cross: the 9 EMA crosses below the 21 EMA (
ta.crossunder).
These are moving-average crossover events, not a full trade system. The script does not apply RSI, volume, support/resistance, stop-loss, take-profit, or position-sizing filters.
How to read the chart
- Blue line: 9-period fast EMA.
- Orange line: 21-period slow EMA.
- Green upward triangle below a bar: a bull cross occurred on that bar.
- Red downward triangle above a bar: a bear cross occurred on that bar.
You can create TradingView alerts using the script's two alert conditions:
- Bull — message:
EMA bull cross - Bear — message:
EMA bear cross
When creating an alert, choose whether it should trigger once per bar, once per bar close, or according to your preferred TradingView alert setting. For signals confirmed at candle close, use a bar-close alert frequency.
Markets and timeframes
The code does not restrict the indicator to a symbol class or timeframe, so it can be applied to any TradingView market with price data. The 9/21 EMA pair will react more frequently on lower timeframes and more slowly on higher timeframes; evaluate the behavior on the specific market and timeframe you intend to use.
Limitations
- This is an indicator, not a TradingView strategy: it does not place orders and has no Strategy Tester performance report.
- EMA crossovers are lagging by design because they are derived from past and current prices.
- A crossover visible during an open, real-time candle can disappear before that candle closes as price changes. Closed-bar markers are based on completed historical bar data.
- The script does not identify trend strength, market regime, liquidity, news events, risk levels, or whether a crossover is suitable for a trade.
- This page is educational and not financial advice. Use TradingView Strategy Tester or your own validated process as the source of truth for live results.

Common questions.
What does Live V23-2 Test detect?▾
It detects crossings between a 9-period EMA and a 21-period EMA. A cross above is marked as a bull cross, while a cross below is marked as a bear cross.
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 below bars mark bull crosses; red downward triangles above bars mark bear crosses.
Can I change the EMA lengths?▾
Not in this version. The source code sets the fast EMA to 9 periods and the slow EMA to 21 periods, with no input controls.
Does this indicator repaint?▾
It does not use future-data or lookahead logic. However, on an open real-time candle, a crossover can appear and then disappear before the candle closes; bar-close alerts help use confirmed candle signals.
Does Live V23-2 Test place trades or include stop losses?▾
No. It is an indicator with plots, shapes, and alert conditions only; it does not call strategy entries or exits and does not define stops, targets, or position sizing.
Is this financial advice, and where can I verify results?▾
No, this indicator and its signals are not financial advice. It has no built-in strategy results, so TradingView Strategy Tester—or an equivalent independently validated testing process—is the source of truth for historical and live results.
