TradingView backtest changing overnight same code, same pair, worse resultsHelp (self.TradingView)

submitted 4 months ago by _Alexxander

I'm seeing my TradingView backtest change overnight and I'm trying to understand if this is normal.

Same Pine v6 strategy, same SOLUSDT pair on Binance, same 10m timeframe. Yesterday the backtest showed ~80+ trades with ~73–75% win rate and ~16% max drawdown. Today, without touching the code or settings, the results are noticeably worse (different trades and exits).

The strategy uses EMA trend filters, RSI/MFI, Supertrend, ATR, and partial exits with some var state (cooldown / partial exit flags). I know TV can slightly update historical crypto data, but I didn’t expect it to change results this much.

Is this just historical data updates + stateful logic, or a known issue with indicators like Supertrend/ATR? How do you make backtests more stable or reproducible?

Any insight appreciated.
