Shorting intraday

How can place a order for shorting at a lower trigger price in intraday

I believe you are asking for equities. One can use intraday products mis/co to sell them.

Ok yes…but what I wonder is if an short order can be placed for a trigger price lower than the current price. I intend suppose to sell a share intraday at 95 as trigger for which the current price is 100. When I put mis order it gets executed at 100 itself rather than wait for trigger of 95

Use SL or SL-M order to sell below the market price. Check this.
