Hello good. Here you have an example.

// ===========================
// Trail Stop steps
// ===========================
triggerDistance = 50
if not onmarket then
   MoveToBreakEven=0
endif
// Example entry/exit condition
conditionsEntry=close CROSSES OVER Average[20](close)
conditionsExit=close CROSSES UNDER Average[20](close)

IF NOT ONMARKET AND conditionsEntry THEN
   BUY 1 CONTRACT AT MARKET
   stoploss = close-triggerDistance*pointsize
   newStopLevel = close + (triggerDistance * pointsize)
   set stop price stoploss
ENDIF

// Management of open position
IF LONGONMARKET THEN
   // Move stop to breakeven
   IF close >= newStopLevel and MoveToBreakEven=0 THEN
      MoveToBreakEven=1
      stoploss=positionprice //breakeven
      newStopLevel = newStopLevel+triggerDistance*pointsize
      set stop price stoploss
   ENDIF
   // Trail stop
   //   if close >= newStopLevel + (triggerDistance * pointsize) and MoveToBreakEven=1 then
   //      stoploss = newStopLevel
   //      newStopLevel = newStopLevel+triggerDistance*pointsize
   //      set stop price stoploss
   //   endif
   // Exit
   if conditionsExit then
      sell at market
   endif
ENDIF

// ===========================
// Graphic

// Trailing Stop and Next Level
graphonprice newStopLevel coloured(0, 0, 255) AS "NextLevel"
graphonprice stoploss coloured(255, 0, 0) AS "Trail Stop"

I changed your code so that it now has 50-point SL and 100-point TP. In addition I added a couple of ENDIFs at the end to run it properly.

I also made a few further changes:

//————————————————————————-
// Main code : US Tech - 3 mins
//————————————————————————-
// Definition of code parameters
DEFPARAM CumulateOrders = False // Cumulating positions deactivated

// Prevents the system from creating new orders to enter the market or increase position size before the specified time
noEntryBeforeTime = 153300
timeEnterBefore = time >= noEntryBeforeTime

// Prevents the system from placing new orders to enter the market or increase position size after the specified time
noEntryAfterTime = 153600
timeEnterAfter = time < noEntryAfterTime

// Prevents the system from placing new orders on specified days of the week
daysForbiddenEntry = OpenDayOfWeek = 6 OR OpenDayOfWeek = 0

triggerDistance = 50
once MoveToBreakEven=0

// Conditions to enter long positions
indicator1 = SAR[0.02,0.02,0.2]
c1 = (low > indicator1)
c2 = (open < close)
c3 = (close[1] > open[1])
c4 = Close - open > 25
c6 = high - close < 35

IF (c1 and c2 and c4 and c6) AND timeEnterBefore AND timeEnterAfter AND not daysForbiddenEntry THEN
BUY 1 PERPOINT AT MARKET
//stoploss = close-triggerDistance*pointsize
//newStopLevel = close + (triggerDistance * pointsize)
set stop   ploss   50
SET TARGET pPROFIT 100
MoveToBreakEven=0
ENDIF

// Conditions to enter short positions
indicator2 = SAR[0.02,0.02,0.2]
c7 = (high < indicator2)
c8 = (close < open)
c9 = (close[1] < open[1])
c10 = Open - close > 25
c12 = close - low < 35

IF (c7 and c8 and c10 and c12) AND timeEnterBefore AND timeEnterAfter AND not daysForbiddenEntry THEN
SELLSHORT 1 PERPOINT AT MARKET
//stoploss1 = close+triggerDistance*pointsize
//newStopLevel1 = close - (triggerDistance * pointsize)
set stop   ploss   50
SET TARGET pPROFIT 100
MoveToBreakEven=0
ENDIF

// Management of open position
IF LONGONMARKET THEN
// Move stop to breakeven
IF ((close - TradePrice) >= triggerDistance*pointsize) and MoveToBreakEven=0 THEN
MoveToBreakEven=1
set stop breakeven
endif
endif
IF shortONMARKET THEN
// Move stop to breakeven
IF ((TradePrice - close) >= triggerDistance*pointsize) and MoveToBreakEven=0 THEN
MoveToBreakEven=1
set stop breakeven
endif
