Test the strategy ChatGPT gave you
Paste it in, copy the prompt into your AI, then paste its answer back and run the backtest.
Your AI does the rewriting.
A strategy from ChatGPT is usually Pine Script for TradingView, a Python script, or a list of rules in plain English. None of those run in TraderPier as they are. Your own AI can translate them, if it knows how strategies are written here.
1. Paste what you have
Code or plain-English rules, straight from the chat.
2. Copy the prompt
Paste it into ChatGPT, Claude or whatever AI you use and copy what it sends back.
3. Run the backtest
Paste that into a blank strategy and run the backtest. You’ll see every trade it took on the chart.
Some of it won’t carry over.
Plots, labels and alerts get dropped, and your AI will list what it left out. If your Pine uses request.security, check it. It can peek at the daily close before the day’s over, and that makes the backtest look better than it really was.
Questions
Do I need an account?
Not to get the prompt. Without an account you get one backtest a day, and nothing is saved. A free account backtests the last 30 days and keeps the runs you save.
Does TraderPier send my code to an AI?
No. The prompt is built in your browser and goes only to the AI you paste it into.
What if the answer doesn’t run?
Paste the error back to your AI and ask it to fix the strategy. Then paste the new answer into the same blank strategy.
Can TraderPier write the strategy for me?
Yes, on Trader and Quant. Spyglass, the AI quant on your desk, builds strategies and indicators on your own chart, tests them, and takes them to paper or live. The prompt on this page works on every plan.
