Something is missing in my "Friday Sell-off"

  This is my first backtest, just trying to create a simple test to take a look at sell-offs in S&P500 during the last 45 minutes on Fridays.

  It seems that I am missing something as I don’t get any results.. I want to look at in in the 5 minutes timeframe and I’ve put in MA8 and MA16, I want to enter a short position (and vice versa for long) when MA8 crosses under MA16 and I want it to exit the position when price goes over MA8 or 10 minutes after closing time of the stock exchange (which in my case is 22:10 as I’m located in GMT+1). Attached you can see a pic of what I’m looking to capture, however the attached pic is of a Thursday but it is just to show you what I’m looking for.

  What am I missing?

  Thanks in advance for any help! 🙂

  Something wrong in your conditions:

  graph c1 AND timeEnterBefore AND timeEnterAfter AND not daysForbiddenEntry coloured (0,200,0) graph c3 AND timeEnterBefore AND timeEnterAfter AND not daysForbiddenEntry coloured (200,0,0)

  1 2	graph c1 AND timeEnterBefore AND timeEnterAfter AND not daysForbiddenEntry coloured (0,200,0) graph c3 AND timeEnterBefore AND timeEnterAfter AND not daysForbiddenEntry coloured (200,0,0)

  Don’t return any valid signals in backtests. You should test each of all your conditions, to know which one prevent a signal to be valid.

  Thanks for answering!

  What do you mean by testing all of the conditions? Am I only testing one right now?

  I think Nicolas means for you to backtest 1 condition and then include a 2nd condition and then a 3rd etc. When you include a condition which stops trades then you know that is the condition with the error?

  This is all conditions that trigger a BUY order:

  c1 AND timeEnterBefore AND timeEnterAfter AND not daysForbiddenEntry

  All these conditions are not met at the same time and that’s why you never get any long entry. I suggest to GRAPH one condition by one in backtests to know why it happens.
