Trading View Pine Strategy Requirement

We have a trading view strategy we'd like to amend to be strategy close rather than strategy exit. We want to be taking through the BBMA line from a higher timeframe in order to use this in the [login to view URL] "when =" statement. On strategy close, we want to exit a trade when price closes below the BBMA line (with a tolerance amount built in via a new variable) BollingerCrossTolerance = input(title="Strategy Bollinger Cross Tolerance", defval=20, type=[login to view URL], minval=0.0) Final strategy close statements will look something like this: [login to view URL]("sell", when = (close < basis + BollingerCrossTolerance)) [login to view URL]("buy", when = (close > basis - BollingerCrossTolerance)) I can send whole script anyway.
