  Hello!

   

  I am coding a Higher High Higher Close + Lower Low Lower Close indicator which tells me when some conditions are met.

  I want to tell the indicator only to give a HHHC if the last one was LLLC and vice versa.

   

  This is the code so far:

  //defparam CALCULATEONLASTBARS=20 if on=1 then //stoch=Stochastic[12,3](close) atr=AverageTrueRange[10](close)[1] ema=dema[20](close) //signalchain=signal=0 and signal[1]=0 and signal[2]=0 and signal[3]=0 realbody=abs(open-close) //averagebody=average[3](realboody) body=realbody[1]>range[1]/4 emaneg= ema[2]>ema[10] and low[1]<ema[1] and open[2]>ema[2] emapos=ema[2]<ema[10] and high[1]>ema[1] and open[2]<ema[2] lllc=low[1]<low[2] and close[1]<close[2] hhhc=high[1]>high[2] and close[1]>close[2] if hh[1]=1 and body and lllc and emaneg then // and signalchain drawtext("LL LC",barindex[1],high[1]+atr,SansSerif,standard,12)coloured(255,50,50) drawarrowdown(barindex[1],high[1])coloured(255,50,50,150) //signal=1 ll=1 elsif ll[1]=1 and body and hhhc and emapos then //and signalchain drawtext("HH HC",barindex[1],low[1]-atr,SansSerif,standard,12)coloured(0,200,0) drawarrowup(barindex[1],low[1])coloured(0,200,0,150) //signal=1 //else //signal=0 hh=1 endif endif return ema as "ema"

  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

  //defparam CALCULATEONLASTBARS=20   if on=1 then   //stoch=Stochastic[12,3](close) atr=AverageTrueRange[10](close)[1] ema=dema[20](close)   //signalchain=signal=0 and signal[1]=0 and signal[2]=0 and signal[3]=0     realbody=abs(open-close) //averagebody=average[3](realboody) body=realbody[1]>range[1]/4 emaneg= ema[2]>ema[10] and low[1]<ema[1] and open[2]>ema[2] emapos=ema[2]<ema[10] and high[1]>ema[1] and open[2]<ema[2]   lllc=low[1]<low[2] and close[1]<close[2] hhhc=high[1]>high[2] and close[1]>close[2]     if hh[1]=1 and body and lllc  and emaneg then // and signalchain drawtext("LL LC",barindex[1],high[1]+atr,SansSerif,standard,12)coloured(255,50,50) drawarrowdown(barindex[1],high[1])coloured(255,50,50,150) //signal=1 ll=1   elsif ll[1]=1 and body and hhhc and emapos then //and signalchain drawtext("HH HC",barindex[1],low[1]-atr,SansSerif,standard,12)coloured(0,200,0) drawarrowup(barindex[1],low[1])coloured(0,200,0,150) //signal=1 //else //signal=0 hh=1 endif     endif return ema as "ema"

  I have tried giving the different conditions variables as hh=1 and ll=1 and test if condtions are met  but what happens is all my drawings disapear so i guess ive done something wrong.

   

  Please help!

  This is without hh=1 and ll=1 conditions:

   

  //defparam CALCULATEONLASTBARS=20 if on=1 then //stoch=Stochastic[12,3](close) atr=AverageTrueRange[10](close)[1] ema=dema[20](close) //signalchain=signal=0 and signal[1]=0 and signal[2]=0 and signal[3]=0 realbody=abs(open-close) //averagebody=average[3](realboody) body=realbody[1]>range[1]/4 emaneg= ema[2]>ema[10] and low[1]<ema[1] and open[2]>ema[2] emapos=ema[2]<ema[10] and high[1]>ema[1] and open[2]<ema[2] lllc=low[1]<low[2] and close[1]<close[2] hhhc=high[1]>high[2] and close[1]>close[2] if body and lllc and emaneg then // and signalchain drawtext("LL LC",barindex[1],high[1]+atr,SansSerif,standard,12)coloured(255,50,50) drawarrowdown(barindex[1],high[1])coloured(255,50,50,150) //signal=1 elsif body and hhhc and emapos then //and signalchain drawtext("HH HC",barindex[1],low[1]-atr,SansSerif,standard,12)coloured(0,200,0) drawarrowup(barindex[1],low[1])coloured(0,200,0,150) //signal=1 //else //signal=0 endif endif return ema as "ema"

  Each time you find a new lllc give ‘signal’ variable a -1 value and each time you find a new hhhc signal give ‘signal’ variable a 1 value. Test this variable accordingly before giving a new signal.

  Thank you! So for lllc to be detected it should be “if signal[1]=1 then”? And vice versa?

  OK so i added “once signal=1” and now it seems to work fine. Was that correct? I dont quite understand the logic behind this command 😀

  “signal” is just a dummy variable to tell your program what was the last thing you plotted on your chart (an arrow up or an arrow down).

  I understand that 🙂 But without me adding the “once” command nothing happened – that was my questions.

   

  Anyway – many many thanks! Really appreciate it!!
