Hi DIMITRIS,
Thanks for your help!
I see now what I was doing wrong. The structure requires a work-
around, using what you call "cond1, cond2," etc. I was trying to do
something more direct with the code, which did not work. Collecting
all timeframe conditions before writing the BUY/SELL signal code is
the solution, it seems. I will write a revised exploration and
hopefully test it on Sunday eve. I may have a followup post at that
time.
BTW, the interesting thing about this code is that the index signals
you would intuitively think would work, don't backtest so well. I am
assuming this is because I need to look at index signals across
multiple timeframes. Optimization should offer some interesting
insight as to how the market reacts seasonally and in long-term
trends, across these index timeframe signals.
I will also be exploring whether something as sensitive as the
Heikin-Ashi haDiffCO or Tom DeMark Range Expansion Index will work
better for hourly trading, over something like stochastics or MACD,
for the index signals. So far, I've (visually) noticed seemingly
contradictory overlaps work well for index IFT-RSI across multiple
timeframes -- when the daily is coming down, and the hourly is
oversold == BUY hourly. To me, this says the market is "tight" right
now, vs. "loose." Loose would mean both IFT-RSI's could be oversold
before signalling an hourly BUY.
Best regards,
Bman
