Quick Question Gents ?

[number2allover]

Hi ,

I'm 3 months in and improving my trades ! More so on the emotional side.

Can I ask a stupid question ?? I've fried enough brain cells thinking about it but I need guidance.

The market matches layers and backers at whatever price they match, so for example a back of 10 is matched with a lay of 10.

I know the 10 on the lay side has whatever liability.

Question :

If half any traded price is back money and the other half is lay , what makes the price go up and down ?

If I am correct is the answer if say, if this was the only money in the market, at price 2.50 is blank (blue on reverse ladder) and I place a back order of 100, if on the pink side their is 20 at each of 2.48/2.46/2.44/2.42/2.40 , does my order swallow each 20, effectively moving the price down to 2.40 ?

I'm a very visual learner so with the vast volume of trades and movement on the ladder I'm getting lost.

Thanks for your time ,
