Creating custom real-time stock signals is a crucial aspect of algorithmic trading, allowing traders to respond promptly to market movements and make informed decisions. TradingView, a popular platform among UK traders, offers a robust alert system that can be leveraged to build custom real-time stock signals. This guide walks you through creating custom real-time stock signals in TradingView, incorporating technical indicators such as the Relative Strength Index (RSI), Moving Average Convergence Divergence (MACD), and volume filters, all tailored to UK market hours.

Understanding the Basics of TradingView Alerts

TradingView's alert system lets you set up notifications based on various conditions, including price movements, technical indicators, and economic news. Alerts can be configured to trigger during UK market hours, which typically run from 8am to 4:30pm GMT, Monday to Friday. For example, you might set an alert to trigger when the FTSE 100 index crosses above its 50-day moving average during UK market hours.

Setting Up RSI-Based Alerts

The RSI is a widely used technical indicator that measures the magnitude of recent price changes to determine overbought or oversold conditions. Use these parameters for RSI-based alerts in TradingView: RSI(14) crosses above 70 (indicating an overbought condition) or RSI(14) crosses below 30 (indicating an oversold condition). You might set an alert to trigger when the RSI(14) of Barclays stock crosses above 70 during UK market hours, potentially indicating a sell signal.

Incorporating MACD and Volume Filters

Refine your real-time stock signals by incorporating the MACD indicator and volume filters. The MACD is a trend-following indicator that measures the relationship between two moving averages. Set up alerts based on MACD crossovers, such as when the MACD line crosses above the signal line, indicating a bullish trend. Volume filters confirm trend strength—set alerts to trigger when trading volume exceeds a specific threshold, such as 10,000 shares per minute. For example, trigger an alert when the MACD line crosses above the signal line and trading volume exceeds 5,000 shares per minute for Lloyds Banking Group stock.

Example Alert Setup

Consider setting up an alert for Royal Dutch Shell stock, listed on the London Stock Exchange. Configure the alert to trigger when RSI(14) crosses below 30, the MACD line crosses above the signal line, and trading volume exceeds 20,000 shares per minute, all during UK market hours. In TradingView, apply these parameters: RSI(14) < 30, MACD line > signal line, and volume > 20,000 shares per minute, with the alert active between 8am and 4:30pm GMT.

Backtesting and Refining Alerts

After setting up a custom real-time stock signal, backtest and refine it to ensure effectiveness. Use historical data to test alert performance, analysing metrics such as the win/loss ratio, profit/loss ratio, and the number of false signals. Adjust parameters based on results—change the RSI period or volume threshold to improve accuracy. You may find that an alert triggers too many false signals; adjusting the RSI period from 14 to 21 reduces sensitivity and improves reliability.

Continuously refining your alerts helps you create effective custom real-time stock signals that enable informed decisions and prompt responses to market movements.
