TradingView Pine Pro
Paste the Pine Script v6 strategy into the Pine Editor, add it to a chart, read the Strategy Tester, and where its trades differ from MetaTrader 5.
This feature is part of Pro.
TradingView exports a Pine Script v6 strategy (.pine). It can export 107 of 119 parts. The rest are blocked, and the export tells you which ones and why. Getting the source is part of Pro.
Add it to a chart
-
In the Builder toolbar, choose TradingView (Pine).
TradingView (Pine) selected in the Builder toolbar. -
Click Download .pine. The file is saved as
EA_Builder.pine. -
In TradingView, open a chart of the symbol and timeframe named on the
Checked under:line at the top of the file. Use a symbol your account has data for. -
Open the Pine Editor at the bottom of the chart and clear it.
-
Paste the whole file. The first line is
//@version=6. -
Click Add to chart. The strategy is drawn on the chart and the Strategy Tester tab shows its results.
How the script decides
The script runs once per bar, at the bar close. Entries and exits are orders that TradingView fills at the next bar open. Stop loss, take profit, limit and stop orders can still hit inside a bar. The script sets calc_on_every_tick = false and process_orders_on_close = false in the strategy() call to make this so.
The last closed bar is read as [0] in the code, which is “Shift 1” in the Builder. A part that reads the forming bar (Shift 0) is blocked.

Differences from MetaTrader 5
These are stated in the header of every .pine file under WHAT IS NOT EXPRESSED.
| Topic | In Pine |
|---|---|
| Spread | Pine candles carry no spread, so it cannot be applied. |
| Swap | Pine strategies have no swap. |
| Minimum stop distance | Pine has no broker stop level. |
| Positions | Pine keeps one net position. An opposite entry reverses it, so there are no hedged or two-sided positions. |
| Trailing stop and break-even | Evaluated at the bar close. MetaTrader 5 does it on every tick. |
| Indicator start values | EMA and RMA start values differ slightly from MetaTrader. The values converge. |
| Gaps | TradingView applies its own fill model. |
| Currency conversion | TradingView applies its own conversion. |
Pine also does not support deciding inside a bar, more than one symbol, reading another timeframe or the measured spread. These parts are listed in Blocks that can’t be exported.
Read the Strategy Tester
Open the Strategy Tester tab under the chart. Overview shows the net profit and drawdown. List of trades shows every trade with its entry and exit. Compare the list with the trades from the Miner.
A few details that the report cannot show:
- The history you can read depends on your TradingView plan and the data of the exchange behind the symbol. The Miner uses its own price data.
- A free plan cannot export the trade list as a file.
Results are an approximation of past data. They do not predict future results.
Match status
There is no match mark for Pine. A checked copy of the script has compiled in TradingView, but its trades have not been confirmed to match MetaTrader 5. The header of every file reads Match with the platform tester: not verified. See Match check.
If it will not compile
- Check that the whole file is pasted, starting with
//@version=6. - Read the message in the Pine Editor console. The first error is usually the cause.
- If you changed the file by hand, undo your change and add it to the chart again.
Next steps
- Read Blocks that can’t be exported for the parts Pine cannot take.
- Read Match check for the current status.
- Go back to the Export overview.
