Question on Long positions

I am new to this concept. Can someone please explain?
I see in morning hours that there is stock that is trading at 160 and I believe that this will touch 166 in afternoon trading hours. I would like to make money here. Is this called intraday trading or day trading? Is this also called taking long position or margin sell?
I have ICICI direct and I dont understand if I should use margin buy or margin sell to achieve the above trade.
And what data do I enter in the screen. If the current market price is 160 and I believe that it will touch 166 then what is the limit price and stop loss trigger price?
Please explain in detail.

If you sell the same day then it's intraday.

Long position is where you keep the stock for several months/years before selling.

The said stock is currently trading at 160, which you believe to jump Rs. 6 by afternoon is a rise of 3.75% which USUALLY (not always, usually) doesn't happen unless there is a big news backing it. Have some realistic profit expectations.

Intraday and day trading are synonymous with each other.

Delivery means buying stocks and holding them for more than one day. If you buy stocks today and sell it tomorrow or 5 years from today, it is called delivery.

Long position is the term used when you are first buying a stock and hoping to sell it at a higher price later on. Short position is the term used when you are first selling a stock at a higher price and hoping to buy it later on at a lower price.
Long positions can be intraday or delivery.
In India, short positions can be only intraday in stocks.

Margin is used when you want to buy stocks worth more than the cash you have in your account.
I did not use ICICIDirect before.
Your trade can be executed by placing a buy limit order at 160 in the morning.
You can check the trade book to see if the above trade is executed or pending.
Once the above trade is executed, you can then place a normal sell limit order at 166. This will sell the shares if the share price reaches 166 in the afternoon.
If they don't reach 166 and you want to sell the shares during the same day, you can place a sell order any time before market closing at the price at which the stock is trading.

Stop Loss is an order used to minimise your losses if the stock does not behave according to your predictions.
Ex. You buy the stock at 160. The stock goes down to 159.
You then feel as if the stock won't reach 166 and want to cut your losses if it goes down to 158. Then you can place stop loss sell order at 158 and Stop loss trigger price as 158.1. This will sell your shares at 158 if the share goes down to 158.1.

Thanks Raghav.
I was under the impression that i can't do intraday trading with normal buy and sell because i thought i can sell only after t+2 days. That is i can sell only after the stock has delivered to me.
And i was under the impression that i HAVE to use margin buy/sell for intraday trading.
Sound like i cannot sell them between buy date and delivery date? but can sell them on the buy date itself or after the delivery date?
Can you please clarify?

You can sell liquid (actively traded) stocks even between buy date & delivery date as your broker(in your case, ICICIDirect) will have enough stocks with him to deliver your sell orders. This is called Buy Today,Sell Tomorrow (BTST) or ATST or any other term as defined by broker. You can confirm with ICICIDirect customer care how to place this type of sell order for the shares which you have purchased and not yet delivered in your demat account.
