To write code, please use the <> “insert PRT code” button to make code easier to read. Thank you.

Moreover this is not an indicator, but a strategy, so I will move the topic to ProOrder Support.

The two combined:

Bolld=ExponentialAverage[20](open)-2*std[20](open)
Bollu=ExponentialAverage[20](open)+2*std[20](open)
nbpoint=25.4
c1 = (high > Bollu+nbpoint*pointsize)
IF c1 AND Not OnMarket THEN
   SELLSHORT 1 PERPOINT AT MARKET
ENDIF
c2 = (low < Bolld-nbpoint*pointsize)
IF c2 AND Not OnMarket THEN
   BUY 1 PERPOINT AT MARKET
ENDIF
 // Stops and targets
SET STOP pLOSS nbpoint
SET TARGET pPROFIT 19

This is an example of how to put an order to breakeven when price reached x% of the takeprofit value, and close part of the position at the same time:

defparam cumulateorders=false

// --- settings
amount = 2 //amount of contract/lot/shares to open for each order
takeprofit = 30 //takeprofit in points 
stoploss = 60 //stoploss in points 
BreakevenAt = 25 //percent achieved of target to move stop to entry (breakeven)
PointsToKeep = 1 //how much pips/points to keep in profit above of below our entry price when the breakeven is activated (beware of spread)
Lot2Close = 1 //amount of contract/lot/shares quantity to close when breakeven occurs
// --- end of settings

upper = BollingerUp[20](close)
lower = BollingerDown[20](close)

//strategy 
if high crosses over upper then 
sellshort amount contract at market 
endif 
if low crosses under lower then 
buy amount contract at market 
endif 
set target pprofit takeprofit
set stop ploss stoploss

//reset the breakevenLevel when no trade are on market
IF NOT ONMARKET THEN
breakevenLevel=0
ENDIF

startBreakeven =  takeprofit*(BreakevenAt/100)//how much pips/points in gain to activate the breakeven function?
// --- BUY SIDE ---
//test if the price have moved favourably of "startBreakeven" points already
IF LONGONMARKET AND close-tradeprice(1)>=startBreakeven*pipsize THEN
//calculate the breakevenLevel
breakevenLevel = tradeprice(1)+PointsToKeep*pipsize
ENDIF

//place the new stop orders on market at breakevenLevel
IF LONGONMARKET AND breakevenLevel>0 THEN
SELL AT breakevenLevel STOP
if countoflongshares=amount then 
sell Lot2Close contract at market
endif 
ENDIF
// --- end of BUY SIDE ---

// --- SELL SIDE ---
//test if the price have moved favourably of "startBreakeven" points already
IF SHORTONMARKET AND tradeprice(1)-close>=startBreakeven*pipsize THEN
//calculate the breakevenLevel
breakevenLevel = tradeprice(1)-PointsToKeep*pipsize
ENDIF

//place the new stop orders on market at breakevenLevel
IF SHORTONMARKET AND breakevenLevel>0 THEN
EXITSHORT AT breakevenLevel STOP
if countofshortshares=amount then
exitshort Lot2Close contract at market
endif
ENDIF
// --- end of SELL SIDE ---
