How to Backtest on TradingView

TradingView in five lines

On TradingView the rule is a short script in Pine, TradingView's own language, added to the chart, and the Strategy Tester panel underneath counts what it did. It needs the script, a symbol and a timeframe, and it runs over the bars the chart has loaded. It gives back arrows on the bars where the script bought and sold, an Overview of totals, and a list of trades. The one setting to know is the date range, because by default the test covers only the loaded bars. The example rule, buy at 10:00 and sell at 18:00, written in six lines and run on 17 to 21 August 2026, made 39.0 pips, where a pip is the fourth decimal place of the price; the week after, in the earlier paper, it lost 56.7.

The rule as six lines

Here is the rule as a script, six lines of Pine in the editor. The first line names the language version and the second names the strategy; the third and fourth say buy at the 10:00 bar, the fifth and sixth say close at the 18:00 bar. Nothing is hidden in the frame. One thing to set before trusting it: the chart's clock, because hour is read off the clock the chart shows, and a chart set to New York time would buy at a different bar from one set to the feed's time. If a rule cannot be written in six lines like these, it was not a rule yet, and there is nothing to test.
