From a trading idea to a strategy
A TradingView strategy needs more than an entry signal because Xen also needs to know when to exit, which trade directions are allowed, how positions are sized and what risk controls to apply, along with any execution assumptions that matter inside TradingView's broker emulator.
You can describe all of this in plain English and, where important details are missing, Xen can clarify them or organise a larger idea into stages before generating the complete Pine Script v6 source. The aim is not simply to produce code that looks convincing, but to create a strategy you can compile in TradingView and check against the rules you originally specified.
Build a Pine Script v6 strategy that enters long when the 20 EMA crosses above the 50 EMA and RSI is above 55, then enters short when the opposite conditions occur. Confirm signals at bar close, allow one position at a time and use configurable ATR-based stop-loss and profit-target distances.
Describing the behaviour
A broad request such as “build an EMA strategy” leaves Xen to make too many decisions. Two traders can use the same indicators yet expect completely different entries, exits and order management, so include the details that would change when and how a trade is placed.
Entry rules
State the exact event that opens a trade, the permitted direction and whether a signal must be confirmed when the bar closes.
Exit rules
Describe opposite-signal exits, stops, targets, trailing logic, break-even rules and any time-based exit.
Position behaviour
Specify sizing, pyramiding and whether the strategy may reverse directly from long to short.
Test assumptions
Identify the intended market, timeframe, session, commission and slippage assumptions where they matter.
A small strategy can often be described in one request, while a system with several filters, order rules and related features is better handled through Xen's Build Planner, which asks up to three focused questions and creates an ordered plan. Starting with a working baseline makes it much easier to compile the script and check its behaviour before adding the remaining features.
A practical TradingView AI workflow
1. Create a strategy project
Sign in to TradingView Xen and select Build Strategy when you want to create a new strategy rather than modify or convert existing source, then enter the trading rules or use Prompt Builder if the idea needs clarification and a staged plan.
2. Generate the Pine Script v6 baseline
Xen returns one complete Pine Script file rather than disconnected fragments, so review the strategy declaration, inputs, entries and exits together and check that no unrequested trading rules have been introduced.
This excerpt only shows the basic signal logic; protective orders, sizing, inputs and the full trade lifecycle still need to be reviewed in the complete generated source.
3. Compile in TradingView
Copy the complete source into TradingView's Pine Editor and save it, using TradingView's compiler as the final check that the script is valid Pine Script. Read the warnings as well as the errors because code can compile while still containing inconsistent calculations, unsuitable order logic or unintended repainting behaviour.
4. Correct compiler errors with the complete source
If Pine Editor reports a diagnostic, send the exact message and the current complete script to Xen's Pine error repair workflow so it has the context needed to correct the problem, then compile the revised version in TradingView again.
5. Add the strategy to a chart
Confirm that entry and exit markers appear where the written rules say they should, test more than one market period and inspect individual trades because a headline performance number cannot tell you whether a stop fired on the intended bar or a session filter excluded the correct signals.
6. Review Strategy Tester evidence
Set commission, slippage, initial capital and order size deliberately, then examine the List of Trades alongside the summary statistics. Net profit on its own says very little without the drawdown, number of trades, average trade, market exposure and sensitivity to the selected date range.
7. Refine one feature at a time
Return to the same Xen project when you want to add a filter, change the risk management or correct unexpected behaviour. Make one focused change at a time so it can be compared with the last tested version, using Xen's saved revisions if you need to inspect or restore earlier source.
Check execution with backtests
A backtest can look convincing for the wrong reasons because Pine strategies run within TradingView's execution model, which may differ from the platform or discretionary method on which the idea was based. Check whether the logic runs at bar close, when orders are filled and whether the stop and limit assumptions match the intended design.
Take extra care with higher-timeframe data because request.security() can behave differently on historical and real-time bars depending on the expression, offset and look-ahead setting. Before trusting a strong equity curve, check the source for future information and watch how its signals behave as new bars form.
Repainting can also come from unconfirmed-bar calculations, pivot confirmation, changing higher-timeframe values or history-dependent functions used inconsistently. Define the expected behaviour in the original requirements, inspect the generated source and, where practical, test it on live or replaying bars.
Use AI as part of the development cycle
Treat the first generated strategy as a baseline and, once it compiles and the basic trades match the specification, ask Xen for focused additions such as a configurable session, another filter or revised stop management, compiling and testing after each meaningful change.
Xen can compare the latest complete Pine Script with the requirements recorded in the project and report which parts appear implemented, partial or missing. Requirements Verification is a static code review rather than a TradingView execution test, so use it alongside Pine Editor, chart inspection and Strategy Tester results.

Common mistakes
A successful compile does not establish that a strategy is profitable, robust or suitable for live trading, while historical simulations may not reproduce liquidity, order priority, spreads, latency or changing market conditions. Results can also be distorted by fitting parameters too closely to one symbol, timeframe or date range.
Use realistic costs and out-of-sample periods, compare the actual trades with the strategy specification and investigate results that appear unusually strong. Xen assists with software development and analysis, but it does not provide trading advice or remove the need for independent testing.
