Fundamental Mechanics of Trade Execution and How price move

Hi there,
i have been trading for almost 5 years.. learned about technicals, mql coding and bit of fundamentals and so on but yet it seems bit difficult to understand how price moves.

Anyone help me with understanding following concepts. there are so many theories(even for supply and demand). so i am confused

1. what will happen when limit orders partially filled or totally filled?
2. what is the roll of limit order in moving the market?
3. what will happen when market orders partially filled or totally filled?
4. what is called iceberg orders?

in simple terms, how price moves?

thanks and sorry for my poor english

bumping.. anybody?

1. Limit orders don't move the market.

2. For orders to get filled at those prices

3. Partially filled orders will sit waiting to be filled. Obviously, filled orders will form volume

4. Iceberg orders....hedge funds and banks need to chop up their orders. If they put a market order in of say 10,000 contracts-in a thin market - their fills will be terrible. So banks cut up their orders to avoid this. This is very broadly how it works.

Has some more information on this.

Personally, I would not get to involved on this.
Just wait for clear trading opportunities.
