Change Stoploss after a specific time

[iimka]

I know how to code a trailing stoploss, for example:

for trade in self.trades:
   if trade.is_short:
      trade.sl = min (trade.sl or +np.inf, self.data.Low * 1.02)

But how can I change the stoploss to the entry price after a specific time? For the below example, black line is my expected stoploss.

Look into Trade.entry_bar (compare it with len(self.data.index)) and Trade.entry_price?

Yes, it is what I want!
for trade in self.trades: print(len(self.data.index)) print(trade.entry_bar) print(trade.entry_price)
