Remember the value at a crossing

  Hello,

  i think my question is simple but I can not get a working answer myself. I want to build a simple system on 5 minutes timeframe that buys when Stochastics (lijnK) crosses over the value 60.  So for example at 14.05 lijnK has value 48.77 en at 14.10 lijnK has value 72.33 so a crossing of the value 60 has occured, the system will go long at 14.15

  Now I want my system to “remember” the value 72.33 from time 14.10. As soon as lijnK crosses under this 72.33 the trade must be closed again. Seems simple.

  I have tried:

  c1 = lijnK CROSSES OVER 60

  c2 = lijnK CROSSES UNDER aa

   

  // Condition to buy

  IF c1 THEN

  BUY 1 SHARES AT MARKET
  lijnK = aa

  ENDIF

   

  // Condition to close longposition

  IF c2 THEN

  SELL AT MARKET

  ENDIF

  So I have stated that lijnK = aa. This is not working, it seems aa is considered to be a variable that I must define for optimising the backtest. I do not want optimalisation, and defining aa as varying from 1 to 100 (with 0.1) does also not help.
  I have also tried several words instead of aa, for example lijnK = lijnKatcrospos but now lijnKatcrospos is also considered to be a variable…

   

  Detail: when i use

  // Condition to buy

  IF c1 THEN

  BUY 1 SHARES AT MARKET
  lijnK = aa

  ENDIF

  the system buys at 14.15   In fact, I do not want the system to remember the value of lijnK at 14.15 but at 14.10….  but I think writing lijnK[1] = aa would be wrong, the systems looks at the crossing of “lijnK”.

  Thanks!

  Hi, assuming you have a line not shown defining your stochastic, like lijnK= stochastic[14,3](close) for example, but maybe with different settings, you can try with:

  lijnK= stochastic[14,3](close) // to maybe change with your stochastic own parameters c1 = lijnK CROSSES OVER 60 // Condition to buy IF c1 THEN aa = close BUY 1 SHARES AT MARKET ENDIF c2 = lijnK CROSSES UNDER aa // Condition to close long position IF c2 THEN SELL AT MARKET ENDIF

  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

  lijnK= stochastic[14,3](close) // to maybe change with your stochastic own parameters   c1 = lijnK CROSSES OVER 60 // Condition to buy   IF c1 THEN     aa = close     BUY 1 SHARES AT MARKET   ENDIF         c2 = lijnK CROSSES UNDER aa   // Condition to close long position   IF c2 THEN     SELL AT MARKET   ENDIF

  Thanks JC that is a very soon answer..

  Yes i used the standard stochastic as given by ProRealTime, but it is in Dutch:

  // Stochastic 14,3,5

  plusHoog = highest[14](high)

  plusLaag = lowest[14](low)

  oscillator = (close – plusLaag) / (plusHoog – plusLaag) * 100

  lijnK = average[3](oscillator)

  lijnD = average[5](lijnK)

   

  In my case lijnD is not used, we are talking about lijnK. This lijnK oscillates between 0 and 100.

  The standard stochastic does not use the term close. It works with lijnK and lijnK[1] and so on….

  The answer you give contains close and I think that will lead to confusion since close refers to price.

  But your answer made me thinking. Maybe I should write:

  c1 = lijnK CROSSES OVER 60

  // Condition to buy

  IF c1 THEN

    aa = average[3](oscillator)

    BUY 1 SHARES AT MARKET

  ENDIF

  c2 = lijnK CROSSES UNDER aa

  // Condition to close long position

  IF c2 THEN

    SELL AT MARKET

  ENDIF

  Hi, you’re absolutly right, big mistake I made in line 8, memorising the value of lijnk at crossing in line 8 should have been aa=lijnk, not aa=close, what it does is memorising into aa the value lijnk has at close of the candle during which lijnk crossed 60.

  And also, yes you could also use the average[3](oscillator) you have, it would work too to memorise its value into aa when c1 true.

  Thanks JC! I will try this. It is actually very funny! At start I wrote lijnK = aa  and that was wrong…. It is just the other way around… I will try later today…
