Sell NIFTY at 11900+ when top is formed for minimum 11320, though the ultimate target can be much bigger. But, that's something for the future
For now, buy NIFTY with an SL of close below 11510 for a target of 11900+. Buy as close to SL as possible.
Close below 11510 might confirm that the top is already done, and the minimum target of 11320 is coming next.
Now can buy again with an SL of 11565. This time if SL hit, then just reverse trade. SL saved target remains 11900+. SL gone, downside target 11320.
If TSL gets hit, short below 11565 only.
