EA based on the London Open Breakout

Hi There

I need an EA that does the following:

a) On any 15min chart, calculate the 'range' (difference between High and Low), 'target' (range*0.5) from 01:00 to 07:45 bars  //Print-out the 'range', 'target' variables as well as 'High', 'Low' and the 'AccountBalance'  

b) Lotsize should be AccountBalance * 'Risk'  //Risk variable should be an externalVariable that I input

c) Place the following pending orders at 08:00 with an expiry of 18:00 if not executed and at a lotsize calculated in (b): 

d) BuyStop order with the following parameters:

- Buy 6 pips above the high calculated in (a) = 'EntryPoint'

- TP = EntryPoint + Target

- SL = High - Target

e) SellStop with the following parameters:

- Sell 6 pips below the low calculated in (a) = 'EntryPoint'

- TP = EntryPoint - Target

- SL = Low + Target

So, for instance if my account balance is 1,000 and the 'Risk' I input is 0.0005 and the EA is attached on the GBPUSD pair with a High of 1.33331 and Low of 1.33124, the EA should output the following and display on chart:

Hi: 1.33331

Lo: 1.33124

Range: 20.7

Target: 10.4

Then the following Pending order should be opened at 08:00 with 18:00 expiry

 Buy 0.5 @ 1.33391

TP @ 1.33495

SL @ 1.33228

Sell 0.5 @ 1.33064

TP @ 1.32961

SP @ 1.33228
