Hi Jaco,
I just stumbled across your MRI indicator. In backtesting
it first looked actually great. Until I realized that you have the ability to
"look into the future". This ability is implied in your AFL code which usesthe
statement
Ref(Close,1)
This looks one period into the future, i.e. the signals
that you think appear, are actually only known one day later. If one corrects
your formula for this flaw, the outcome is actually horrible.
What do you think about this?
There is a great danger of using AFL code that employ
statements that "look into the future". If you are not careful, it may do well
in backtesting, but only due to the fact that when using past data in
backtesting, the "future" is always known already. But as some wise guy said:
"Too bad my broker forces me to trade at the hard right
edge of the chart."
Regards
Al

Hi,
This is a very simple alteration / combination to
the RSI/Momentum indicators which I stumbled on. I call it the
MRI.
What is significant about this indicatoris that
it reaches its peak values a day before the normal RSI reaches its peak value,
which can help a lot in the timing of your purchase. The 30/70 rule is still
applicable, but I include a averaged AFL system for those
interested.
Hope you find it useful.
