I need help to build an EA based on extreme spike indicator

[compass]

How to open the Builder and how to add the indicator to start seting the conditions?
The EA conditions should be:

Start the EA
add manually the input (0 or 2?) in "note2"
Set Lot Size
Set Margin Level
Set PAIR....if necessary...?
Allow any Spike Values from 0 to n
EA must Wait for the FIRST Spike UP
SKIP any Spike Down, in any number of repetitions
On the FIRST Spike UP
EA Must Start Opening SELL Orders in the current chart PAIR,
Untill Margin Level is Down to...300%
EA must not do anything else
Then manually Delete the EA from the chart
