Price Chart Visualization

The Price Chart section provides a visual representation of your backtest trades and alert signals overlaid on actual market data. This is your fastest way to identify patterns and anomalies in signal timing.

---

Overview

The interactive price chart displays:

• Candlestick data — Historical price action for your symbol
• Backtest markers — Signals from your TradingView export
• Alert markers — Real-time signals from webhooks or CSV
• Visual connections — Lines connecting matched signal pairs

This visual approach often reveals issues that are hard to spot in tabular data.

Chart Elements

Candlesticks

Standard OHLC candlestick chart showing:

• Green candles — Bullish (close > open)
• Red candles — Bearish (close < open)
• Wicks — High and low of each period

The timeframe matches your analysis configuration (e.g., 1 minute, 1 hour, daily).

Backtest Signal Markers

Marker	Meaning
🔺 Green triangle up	Long entry signal
🔻 Red triangle down	Short entry or exit signal
Position at candle	Placed at the signal price

These represent where TradingView’s Strategy Tester recorded a trade.

Alert Signal Markers

Marker	Meaning
🟢 Green circle	Buy/long alert
🔴 Red circle	Sell/short alert
Position at candle	Placed at the alert price

These represent when your real-time alert fired.

Match Visualization

When a backtest signal and alert are matched:

• A subtle connecting line may appear
• Markers are positioned at their respective times
• The visual gap shows the time/price drift

Visual Analysis Techniques

Finding Timing Issues

What to look for: Backtest triangles and alert circles that are horizontally separated (different times).

Interpretation:

• Consistent horizontal gap = Timezone offset issue
• Variable gaps = Strategy timing variability
• Gap only in certain periods = Possible webhook issues

Finding Price Discrepancies

What to look for: Backtest and alert markers at different vertical positions (different prices).

Interpretation:

• Small gaps (under 1%) = Normal market noise
• Large gaps = Possible data feed differences
• Gaps during volatility = Expected slippage

Identifying Missing Signals

What to look for: Backtest triangles without nearby alert circles.

Questions to ask:

• Was there an alert that arrived earlier/later?
• Is this during a time when webhooks may have failed?
• Is this a specific signal type (entry vs. exit)?

Identifying False Alerts

What to look for: Alert circles without nearby backtest triangles.

Questions to ask:

• Is this a duplicate of a valid alert?
• Did the strategy recalculate and cancel a signal?
• Is calc_on_every_tick causing premature alerts?

Common Visual Patterns

Pattern: Consistent Offset

Appearance: All alert circles appear exactly X candles to the left or right of backtest triangles.

Meaning: Timezone misconfiguration.

Fix: Adjust timezone offset in Backtesting Upload step, re-run analysis.

Pattern: Clustered Mismatches

Appearance: A specific time period shows many unpaired markers.

Meaning: System issue during that period (webhook down, TradingView issue, etc.).

Fix: Check system logs for that time period, consider excluding from analysis.

Pattern: Entry/Exit Asymmetry

Appearance: Entry signals match well, exit signals often miss.

Meaning: TradingView alert only configured for one signal type.

Fix: Add missing alert conditions in TradingView.

Pattern: Volatility Correlation

Appearance: Mismatches increase during high-volatility candles.

Meaning: Price tolerance too tight for market conditions.

Fix: Increase price tolerance or accept as expected behavior.

Chart Data Sources

The chart pulls data from:

Data Type	Source
Price data	Alpaca API (if connected) or cached data
Backtest signals	Your uploaded TradingView CSV
Alert signals	Webhooks or uploaded alert CSV

Loading States

State	Meaning
Loading spinner	Fetching market data
No data available	Symbol not found or date range issue
Partial data	Some bars missing (weekends, holidays)

Note

Market data requires an Alpaca connection for real-time data. Historical data may be cached for common symbols.

Performance Tips

For analyses with many signals (500+):

1. Disable marker tooltips — Reduces hover calculations
2. Use larger timeframes — Fewer candles to render
3. Narrow date range — Less data to process
4. Filter to problems — Focus on mismatches only

Limitations

• Chart data availability — Depends on market data connection
• Maximum signals — Performance may degrade with 1000+ signals
• Historical depth — Limited by data source retention
• Exotic symbols — Some instruments may not have chart data
