XXL Adding

I would like to build a semi automatic EA , that is described on the attached picture. 

Simple EA that I can attach to any chart.

Any time frame.  

I will decide when to place the first BUY or first SELL order.

After the first order, whatever direction I chose, the EA should add automatically another orders.

The Extra Orders should have the same size as the Master Order.

The new Extra Order should always be added when the closed price of the candle is lower (for SELL) or higher (for BUY) than the previous order.

Please look at the attached picture.

When I click CLOSE ALL, it means Close All Orders at once.

When I click REVERSE  - it means that IF there are Open Orders , they should be all closed and a New Master Order should be open in the opposite direction. 

MASTER STOPLOSS - means that by moving one line I will be able to move ALL STOPLOSS AT ONCE. 

Thank you.
