-- Trades graphs
-- Display bounds for every trade you made with profit and loss bounds.
-- Automatically calculate balanced $$ cost

-- Graph has 3 lines:
-- 1. Green line - 'profit' value.
--    If you overcome of this line you balance increases
-- 2. Blue line - 'zero' value.
--    At this value you trade will have zero balance
--    Note: Blue line exists only if you $$ balance nonzero.
-- 3. Red line - 'possible loss' value
--    Indicates value of acceptable loss.
--    If you overcome this line you must make a dessision to close the deal in MINUS or hope price will grows back...
