Entry and exit based on bollinger bands touches

  Hi, don’t know if this is the right forum, but i’m having trouble finding answers on google.

  I need help with a simple thing in the trading system. How do I write the code so that a position is opened when the price touches the upper bollinger band and closes the position when the price touches the lower bollinger band?

  I have only managed to get the position to open if the candle CLOSES outside the upper bollinger band.

  Grateful for help!

  Hi,

  please take into account forum guidance in yellow box at bottom of this page for subsequent posts, here in particular the “meaningful title” rule to prevent topics being all called “help with…”), thanks. I edit your title “help with code” to replace it by “entry and exit based on bollinger bands touches”.

  We can use pending limit orders placed on bollingerbands to trigger entries at the right price.

  defparam cumulateorders=false if not longonmarket then buy 1 contract at BollingerDown[20](close) limit endif if not shortonmarket then sellshort 1 contract at BollingerUp[20](close) limit endif

  1 2 3 4 5 6 7 8

  defparam cumulateorders=false   if not longonmarket then buy 1 contract at BollingerDown[20](close) limit endif if not shortonmarket then sellshort 1 contract at BollingerUp[20](close) limit endif

  Thank you for the fast response, im new to this, so how exactly would i intergrate this into my code today?

  This is my code:

  // Definition of code parameters DEFPARAM CumulateOrders = False // Cumulating positions deactivated // Conditions to enter long positions indicator1 = ExponentialAverage[200](close) c1 = (close > indicator1) indicator2 = BollingerDown[20](close) c2 = (close <= indicator2) IF c1 AND c2 THEN BUY 0.55 CONTRACT AT MARKET ENDIF // Conditions to exit long positions indicator3 = BollingerUp[20](close) c3 = (close >= indicator3) IF c3 THEN SELL AT MARKET ENDIF // Conditions to enter short positions indicator4 = ExponentialAverage[200](close) c4 = (close <= indicator4) indicator5 = BollingerUp[20](close) c5 = (close >= indicator5) IF c4 AND c5 THEN SELLSHORT 0.55 CONTRACT AT MARKET ENDIF // Conditions to exit short positions indicator6 = BollingerDown[20](close) c6 = (close <= indicator6) IF c6 THEN EXITSHORT AT MARKET ENDIF // Stops and targets SET STOP pTRAILING 16 SET TARGET pPROFIT 16

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42

  // Definition of code parameters DEFPARAM CumulateOrders = False // Cumulating positions deactivated   // Conditions to enter long positions indicator1 = ExponentialAverage[200](close) c1 = (close > indicator1) indicator2 = BollingerDown[20](close) c2 = (close <= indicator2)   IF c1 AND c2 THEN BUY 0.55 CONTRACT AT MARKET ENDIF   // Conditions to exit long positions indicator3 = BollingerUp[20](close) c3 = (close >= indicator3)   IF c3 THEN SELL AT MARKET ENDIF   // Conditions to enter short positions indicator4 = ExponentialAverage[200](close) c4 = (close <= indicator4) indicator5 = BollingerUp[20](close) c5 = (close >= indicator5)   IF c4 AND c5 THEN SELLSHORT 0.55 CONTRACT AT MARKET ENDIF   // Conditions to exit short positions indicator6 = BollingerDown[20](close) c6 = (close <= indicator6)   IF c6 THEN EXITSHORT AT MARKET ENDIF   // Stops and targets SET STOP pTRAILING 16 SET TARGET pPROFIT 16

  So I replace your original entries with the ones I coded above:

  // Definition of code parameters DEFPARAM CumulateOrders = False // Cumulating positions deactivated // Conditions to enter long positions indicator1 = ExponentialAverage[200](close) c1 = (close > indicator1) IF c1 THEN buy 0.55 contract at BollingerDown[20](close) limit ENDIF // Conditions to exit long positions indicator3 = BollingerUp[20](close) c3 = (close >= indicator3) IF c3 THEN SELL AT MARKET ENDIF // Conditions to enter short positions indicator4 = ExponentialAverage[200](close) c4 = (close <= indicator4) IF c4 THEN sellshort 0.55 contract at BollingerUp[20](close) limit ENDIF // Conditions to exit short positions indicator6 = BollingerDown[20](close) c6 = (close <= indicator6) IF c6 THEN EXITSHORT AT MARKET ENDIF // Stops and targets SET STOP pTRAILING 16 SET TARGET pPROFIT 16

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38

  // Definition of code parameters DEFPARAM CumulateOrders = False // Cumulating positions deactivated   // Conditions to enter long positions indicator1 = ExponentialAverage[200](close) c1 = (close > indicator1)   IF c1 THEN buy 0.55 contract at BollingerDown[20](close) limit ENDIF   // Conditions to exit long positions indicator3 = BollingerUp[20](close) c3 = (close >= indicator3)   IF c3 THEN SELL AT MARKET ENDIF   // Conditions to enter short positions indicator4 = ExponentialAverage[200](close) c4 = (close <= indicator4)   IF c4 THEN sellshort 0.55 contract at BollingerUp[20](close) limit ENDIF   // Conditions to exit short positions indicator6 = BollingerDown[20](close) c6 = (close <= indicator6)   IF c6 THEN EXITSHORT AT MARKET ENDIF   // Stops and targets SET STOP pTRAILING 16 SET TARGET pPROFIT 16

  I have tried to play around a bit but don’t seam to get it to work, how do i write the code if i alos want the exit of the trade to trigger when price hits the bollinger band? I assume the principal would be the same with pending limit orders?

  Exit on bollinger bands are already defined in your code, but you are using the Close, you can use a precise price touch as define in the below modification:

  // Definition of code parameters DEFPARAM CumulateOrders = False // Cumulating positions deactivated // Conditions to enter long positions indicator1 = ExponentialAverage[200](close) c1 = (close > indicator1) IF c1 THEN buy 0.55 contract at BollingerDown[20](close) limit set target price BollingerUp[20](close) ENDIF if longonmarket then set target price BollingerUp[20](close) endif // Conditions to exit long positions indicator3 = BollingerUp[20](close) c3 = (close >= indicator3) IF c3 THEN SELL AT MARKET ENDIF // Conditions to enter short positions indicator4 = ExponentialAverage[200](close) c4 = (close <= indicator4) IF c4 THEN sellshort 0.55 contract at BollingerUp[20](close) limit set target price BollingerDown[20](close) ENDIF if shortonmarket then set target price BollingerDown[20](close) endif // Conditions to exit short positions indicator6 = BollingerDown[20](close) c6 = (close <= indicator6) IF c6 THEN EXITSHORT AT MARKET ENDIF // Stops and targets SET STOP pTRAILING 16 SET TARGET pPROFIT 16

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48

  // Definition of code parameters DEFPARAM CumulateOrders = False // Cumulating positions deactivated   // Conditions to enter long positions indicator1 = ExponentialAverage[200](close) c1 = (close > indicator1)   IF c1 THEN buy 0.55 contract at BollingerDown[20](close) limit set target price BollingerUp[20](close) ENDIF   if longonmarket then set target price BollingerUp[20](close) endif   // Conditions to exit long positions indicator3 = BollingerUp[20](close) c3 = (close >= indicator3)   IF c3 THEN SELL AT MARKET ENDIF   // Conditions to enter short positions indicator4 = ExponentialAverage[200](close) c4 = (close <= indicator4)   IF c4 THEN sellshort 0.55 contract at BollingerUp[20](close) limit set target price BollingerDown[20](close) ENDIF   if shortonmarket then set target price BollingerDown[20](close) endif   // Conditions to exit short positions indicator6 = BollingerDown[20](close) c6 = (close <= indicator6)   IF c6 THEN EXITSHORT AT MARKET ENDIF   // Stops and targets SET STOP pTRAILING 16 SET TARGET pPROFIT 16
