On what timeframe do you launch the strategy on please?

If the Low is too close of the order opening price, the broker might reject it due to minimum stop distance.

However, try to use this way of setting the stop at a direct price, with SET STOP PRICE:

c1 = (low < indicator1)
c2 = close > midPrev
c3 = (BBwidth > 50)
c4 = (open[1] > close[1]) and rangeprevious > 3
c5 = (indicator2 > 33)
c6 = ( (Average[20](close) - 2 * Std[20](close)) - low ) > 8
c7 = (Close - open) > 20
c8 = (Close - open) < 30


IF (c1 and c2 AND c3 and c4 and c5 and c6 and c7 and c8) AND timeEnterBefore AND timeEnterAfter AND not daysForbiddenEntry THEN
buy 5 PERPOINT AT MARKET
entryLow = low // Store the low of the candle before the entry candle
SET STOP PRICE entryLow
SET TARGET PROFIT 45
endif

@tradermaker, the reason your live trades open without stop/target is that:

• entryLow is set when the order condition is true, but you only place the stop and target one bar later inside IF ONMARKET THEN.
• On the entry bar, the order is still a pending market order until the bar closes, so ProOrder does not yet know you are ONMARKET and does not send any stop/target at that time.
• On the next bar, entryLow may already have changed (because you overwrite it every time the condition is true), or the condition never runs again, so the stop level is inconsistent or missing.

Solution: set the stop and target immediately when you send the market order, and protect entryLow with NOT LONGONMARKET so it is not overwritten after entry.

Corrected version of your code (core part only):

// Main code : us tech

DEFPARAM CumulateOrders = False
DEFPARAM FLATBEFORE = 143000
DEFPARAM FLATAFTER  = 213000

noEntryBeforeTime = 143000
timeEnterBefore   = time >= noEntryBeforeTime

noEntryAfterTime  = 210000
timeEnterAfter    = time < noEntryAfterTime

daysForbiddenEntry = OpenDayOfWeek = 6 OR OpenDayOfWeek = 0

// Bollinger band width
mid   = Average[20](close)
upper = mid + 2.0* Std[20](close)
lower = mid - 2.0* Std[20](close)
BBwidth = upper - lower

// Mid of previous candle
midPrev = (open[1] + close[1]) / 2
condition = close > midPrev

// Previous candle body
prevBody = close[1] - open[1]

// Bollinger band (again, could be removed as duplicate)
mid   = Average[20](close)
lower = mid - 2 * Std[20](close)
upper = mid + 2 * Std[20](close)

condition = (lower - low) > 4

// Indicators & conditions
indicator1    = BollingerDown[20](close)
indicator2    = RSI[14](close)
indicator3    = BollingerUp[20](close)
rangeprevious = open[1] - close[1]

c1 = close - open > 60
c2 = close[1] < open[1] and close[2] < open[2] and close[3] < open[3]
c3 = close > open[1] and close > open[2] and close > open[3] and close > open[4]
c4 = high - close < 20
c5 = close - low < 172
c6 = low < low[1]

// --- ENTRY BLOCK: send order + stop + target on the same bar ---
IF (c1 AND c2 AND c3 AND c4 AND c5) AND timeEnterBefore AND timeEnterAfter AND NOT daysForbiddenEntry AND NOT LONGONMARKET THEN
   // Store the low of the entry candle only once, at entry
   entryLow = low

   // Send the market order
   BUY 2 PERPOINT AT MARKET

   // Attach stop and target immediately
   SELL AT entryLow STOP
   SET TARGET PROFIT 100
ENDIF

// --- EXIT SAFETY BLOCK: re-apply stop/target every bar while in position ---
IF ONMARKET THEN
   // Re-assert the same stop level and target while the position is open
   SELL AT entryLow STOP
   SET TARGET PROFIT 100
ENDIF

Logic explained:

• NOT LONGONMARKET in the entry block:
  • Ensures entryLow is only set once, on the actual entry candle.
  • Prevents entryLow from being updated on later candles while you are already in a trade.
• Inside the same IF as the BUY … AT MARKET, you immediately place:
  • SELL AT entryLow STOP → explicit stop-loss level is sent with the order.
  • SET TARGET PROFIT 100 → profit target distance is also attached right away.
• The second IF ONMARKET block:
  • Re-applies the same stop and target every bar as a safety net, so if for any reason they get cancelled or modified by the broker, ProOrder keeps sending them while the position is open.

If your broker has a minimum stop distance and entryLow is too close to the entry price, the server can still reject the stop; in that case you will see no stop in the position window even though the strategy is syntactically correct. In such a case you may need to use a slightly further price (e.g. entryLow – 5 points) or SET STOP PRICE with a valid distance.
