Buy and Sell execution Question

#1
Hello Guys,

Since i am new in trading, i got few doubts :)

I want to understand it by an example.

I baught a 200 shares at 42 rs. Now I want to sell it for 45 or above.

I see price reaches to 45 but my order never get executed. How should i place the sell order so that i get executed when my desired price is available.

Furthermore, if price is 45 for all day long and it doesnt get executed. Does this mean there is no buyer?

This is my question about sell order.

Same i want to know about buy order if i want to buy a share at between 39 to 41 rs.

How should i place such order so that i get executed.

Since i place limit order with RL it never get executed :) it says pending pending pending.....

Any help will be highly appreciated. :)

Regards,

Rahul
