local bbType = InputMaTypes(&#039;Type&#039;, SmaType, &#039;&#039;, &#039;BBands&#039;)

--------------------------------------------------------------
-- Data
local ma = MA(maSrc(), maPeriod, maType)
local bb = BBANDS(bbSrc(), bbPeriod, bbDev, bbDev, maType)

--------------------------------------------------------------
-- Charts
local l_bbUpper = Plot(0, &#039;BB Upper&#039;, bb.upper, {c=SkyBlue, w=2}) -- BB Upper
local l_bbLower = Plot(0, &#039;BB Lower&#039;, bb.lower, {c=SkyBlue, w=2}) -- BB Lower
Plot(0, &#039;BB Middle&#039;, bb.middle, SkyBlue) -- BB Middle
PlotBands(l_bbLower, l_bbUpper, SkyBlue(10)) -- Band
Plot(0, &#039;MA&#039;, ma, {c=Orange, w=2}) -- MA line

--------------------------------------------------------------
-- Trading logic
if ma &gt; bb.middle then
  -- look for long entries
elseif ma &lt; bb.middle then
  -- look for short entries
end

-- You might want to separate order handling,
-- TP and SL systems from the upper part.

--------------------------------------------------------------
-- Notes:
-- You have multiple options for BB upper and lower bands:
-- * Stop-loss for entries (lower for longs, upper for shorts)
-- * Breakout type of entry with market order
-- * Determine the range of your entry, TP and SL levels
