10 free Pine Script v5 strategies to test before use

These ten free Pine Script v5 strategies are complete examples you can open, copy and replay yourself. Each one states a single entry and exit rule, so you can check what the code does before you judge any result built on it.

Ten scripts is a small library, not a promise. They cover the families most TradingView users meet first: mean reversion on RSI or Bollinger Bands, trend following on EMA crosses, ribbon alignment and SuperTrend, momentum on MACD, and volatility breakouts on ATR. Every page linked below holds the full v5 source, the rule in plain words and the indicator settings, so nothing is hidden behind a screenshot.

The ten scripts

Read the type column as a description of the rule, not as a recommendation. A reversal script buys a stretch away from a mean; a trend script buys continuation; a volatility script waits for a range to break. Those ideas fail in different markets, which is why the next section matters more than the list itself.

Why pastebin and forum scripts mislead

A pasted script arrives without its history. You see the code, sometimes a screenshot of an equity curve, never the conditions under which that curve was produced. Four problems account for most of the gap between a shared script and a usable one.

Repainting and look-ahead. Calls to request.security can read a higher-timeframe value that was not yet known when the bar closed, especially with lookahead enabled or when barstate.isconfirmed is missing. The signal looks excellent on history because the script is quietly reading bars from the future. The same applies to scripts that redraw a level after the close, so the arrow you see today was not there yesterday.

Costs set to zero. A strategy() declaration without commission and slippage runs on a frictionless tape. On a rule that trades often, the difference between the frictionless list of trades and the same list with realistic costs is the whole point of the test. A shared snippet rarely documents which costs, if any, were used.

Over-optimisation. Parameters such as a 14-period RSI or a 9/21 EMA cross are conventions, and conventions are easy to fit after the fact. When a script comes with tuned numbers but not the number of variants that were tried to find them, you cannot separate a discovered rule from a selected one. Counting every attempt is the only defence, and a pasted file never carries that count.

Missing context. Default pyramiding, position size, session hours, timezone, data source and chart type all change the trade list. A script tested on Heikin Ashi or Renko bars is not the same script on standard candles. Nor does a snippet usually say what happens to the last open position, or whether the strategy closes it at the end of the sample.

None of this makes shared code worthless. It means a script is a hypothesis, not evidence.

How to check a script before using it

Five steps, in order, each one cheap.

1. Read the code and pin the version. Confirm the first line is //@version=5, list every input, and write the entry and exit rules in one sentence each. If you cannot restate the rule without the code, you cannot judge the result.
2. Add costs before you look at the result. Set commission and slippage in the strategy() call or the Properties tab, then compare the trade list, not the net profit line. Two runs with different costs should agree on entries and disagree on outcomes; if entries move, something else changed.
3. Hunt for look-ahead and repainting. Search the source for request.security, lookahead, barstate.isconfirmed and history offsets such as [1]. Then change the chart type and the timeframe and see whether the signals move. A signal that appears and disappears with the chart type is not a signal.
4. Count the trades and open a few. A rule with a handful of trades cannot support a conclusion, and a long list dominated by one winner deserves a closer look at that trade. Check that exits happen when the rule says they should, including the last bar.
5. Replay it on a period you never used to choose the parameters. This is the step most shared scripts skip. Strategy Arena Lab is a free desktop app for Windows and Linux: it imports supported Pine v5, replays it locally, seals the end of the data before the search, counts every variant you try, and returns holds, mirage or inconclusive. Nothing is sent anywhere and no tool places an order. Download it at /en/download.

The Lab is explicit about what it measures. Its documented method compares the trade list with TradingView trade by trade: 258/258, 97/97 and 26/26 trades on 13 October 2026, and 62/62 on a buy stop order with build 0.1.0-249. That parity is a statement about reproduction, not about profit. A strategy that reproduces exactly can still fail out of sample, and the sealed period is where that shows up.

What to do with the list

Start with the family that matches the market you actually follow, not with the script that looks best on a chart. Take one rule, replay it on data you have not seen, then change one parameter and replay again. If the result survives the change and the unseen period, you have a hypothesis worth more work. If it does not, you have saved yourself a subscription to someone else's screenshot.
