Pine Script: Moving from indicator to strategy using dynamic base value and closing position at specified values

Question

I developed a condition when using the "Relative Strength Index" indicator. I can't figure out how to move from the indicator to the strategy and close the position at 350, 13, 349, etc. (please see photo) candles, but the problem is that the base value, I have it is p4, it is not fixed and constantly changes.

//@version=5
indicator(title="Relative Strength Index", shorttitle="RSI", max_bars_back = 2000)

ma(source, length, type) =>
    switch type
        "SMA" => ta.sma(source, length)
        "Bollinger Bands" => ta.sma(source, length)
        "EMA" => ta.ema(source, length)
        "SMMA (RMA)" => ta.rma(source, length)
        "WMA" => ta.wma(source, length)
        "VWMA" => ta.vwma(source, length)

up = ta.rma(math.max(ta.change(rsiSourceInput), 0), rsiLengthInput)
down = ta.rma(-math.min(ta.change(rsiSourceInput), 0), rsiLengthInput)

Answer 1

So, you want to clsoe your position conditionally. In that case, you should use the strategy.close() function.

Something like below:

close_condition = (p4 == 350) or (p4 == 13)

if (close_condition)
    strategy.close("Long")
