Change existing EA TP and SL behaviour

Hello,

I have an EA that is opening buy trades or sell trades, depending on if the candle it was dragged on the chart is bearish or bullish. It can also close trades also depending on if the candle it was dragged on the chart is bearish or bullish. It has some TP and SL settings and also a BE setting. What I like to have now is, that as soon as the EA is dragged on the chart and a new trade is opened, any existing SL and TP of open trades of the current chart and timeframe is moved to the price of the current settings.

Example:

There is buy trade with TP at 1.13 and SL at 1.10 already running on the chart.

Now I drag the EA on the chart and it opens after the close oft he candle a new buy trade with TP at 1.12 and SL at 1.11

Now the TP and SL oft he first trade should also be at 1.12 and 1.11 and no longer be at 1.13 and 1.10.

The logic of the EA does not have to be changed.

Only the following logic: If EA opens a trade and there are already other open trades on the chart, then all trades get the SL and TP of most recently opened trade.
