What to do it stock is breaking its own high after some interval of time?

Suppose

If Marico stock opened at 292 made high of 296
After some ups & downs of 15 min it broke 296 and made high of 300.

Then After some ups & downs of 15 min it broke 300 & made high of 305

What shall one do if stocks are breaking its own high?
Someone suggested me to go for Cover Order.

If you are sure that it’s in uptrend, buy on dips and go long. Put a stop loss order and see how far it goes. Tracking with the help of EMA and MACD will help you out in exiting the positions.

Do you want to buy and sell for intraday?
