Bollinger Strategy

  Hi, can somebody help me with my strategy. I need some modification to optimize it. The change that I need is to make it open a position only if it crosses the middle bollinger line before hand. Example: If I have an open long position and it hits target profit then it only opens a new long position if it crosses the middle bollinger line again, if the price still above the middle bollinger then it should stay inactive.

  Sorry if my English is bad.

  Hello,  in your conditions variables ‘condition1’ and ‘condition4’ , you should test a crossover with the  EMA instead of only testing if close is above or under it. I’ll post codes if you don’t find how to get it.

  Here is the short tricks to made it works like you want it :

  For Long position :

  c1 = (close crosses over indicator1)

  1	c1 = (close crosses over indicator1)

  For Short position :

  c4 = (close crosses under indicator4)

  1	c4 = (close crosses under indicator4)

  Thanks for the reply, but that isn’t what I’m looking for. If I make those changes, then it will trigger an Entry only if it crosses the middle bollinger line and the second conditions kicks in. I need it to cross beforehand. So it will be like this:

   

  Conditions:

  1. The price is over middle bollinger band
  2. Seven days before the high has to be over upper bollinger band

     Enter Long.

  3. If previous position hits target/stop then enter only if the prise moves under the middle bollinger band, then up and condition 1 and 2 kicks in then go long again.

  So your ‘c1’ condition need only to be tested once? At ProOrder strategy startup? If so, all you have to do is to “flag” your first trade with a variable and then make 2 different ‘c1’ conditions :

  • first ‘c1’ : tradedbefore=0 so test only if “Close>EMA50”
  • second ‘c1’ : tradedbefore=1 so test a crossover

  Sorry Nicolas, I can’t  make it work. Can you please write the code for me?

  Here is the final code, I have flagged the first trade with the “tradedbefore” variable set to 1 if a first trade has occurred. If then, the next trade would be taken only if the price crosses above or below the middle bollinger band (a moving average 50 periods in this case).

  // Definition of code parameters DEFPARAM CumulateOrders = False // Cumulating positions deactivated DEFPARAM preloadbars = 0 once tradedbefore=0 GRAPH tradedbefore as "tradedbefore" // Conditions to enter long positions indicator1 = ExponentialAverage[50](close) if tradedbefore=0 then c1 = (close > indicator1) elsif tradedbefore=1 then c1 = close crosses over indicator1 endif indicator2 = ExponentialAverage[50](close)+1.5*std[50](close) c2 = (high[7] >= indicator2) IF c1 AND c2 THEN BUY 1 CONTRACT AT MARKET tradedbefore = 1 ENDIF // Conditions to exit long positions indicator3 = ExponentialAverage[50](close)-1.5*std[50](close) c3 = (low <= indicator3) IF c3 THEN SELL AT MARKET ENDIF // Conditions to enter short positions indicator4 = ExponentialAverage[50](close) if tradedbefore=0 then c4 = (close < indicator4) elsif tradedbefore = 1 then c4 = close crosses under indicator4 endif indicator5 = ExponentialAverage[50](close)-1.5*std[50](close) c5 = (low[7] <= indicator5) IF c4 AND c5 THEN SELLSHORT 1 CONTRACT AT MARKET tradedbefore = 1 ENDIF // Conditions to exit short positions indicator6 = ExponentialAverage[50](close)+1.5*std[50](close) c6 = (high >= indicator6) IF c6 THEN EXITSHORT AT MARKET ENDIF // Stops and targets set target %profit 0.4
