Add a lot multiplication function to my working Grid style EA please

Hi 

As you will see the EA opens multiple buy and sell orders at the same level with different TP's multiple times a set distance apart .

I want to you to add the following to it :

Here is the example of what I want to happen :

When the market is trending   down all the sell orders TP's will be hit leaving the buy orders open.I want the EA to increase the size of the Buy orders by a lot factor of X every set amount of pips it moves away from the first buy order placed.

 So for example :

If the first order opened and price move by say 100pips away from that price I want the EA to start placing buy orders at whatever the original order * the lot factor BUT keep the sells the same size ( Please ask if you need more info about it )   

So if the EA were to plot order every 20 pips and I have lot_Factor of 2  set to take effect every 100pips it would place 5 orders of the same buy size 5 time as the price moved lower and then after going down 100 pips it would only double the buys till it moved down another 100pips and it would double the buys again but leaving the sells at the same volume

 There is a pic attached to see what it looks like when trading  

I want to be able to set the multiplication factor and distance away from original or first order .
