Hi AF,
Sorry, I missed your question earlier! I admit it can be little bit tricky with
timeframes and it takes some time to get use to it.
But your assumptions are not correct. When I use a 1 min chart and I calculate
the 5 min timeframe at 9:03 AM, it's a new bar for the 1 min chart, and we are
60% done on the 5 min bar which period started at 9:00 AM.
I am not sure how others do intraday trading, but I don't sit and wait for
higher TF bars to close. Another advantage in my specific case is that with 1
min data resolution in the higher TFs- the Buy/Sell signals will not "come and
go". I give you an example. Let's say that I have a system which requires
signals from 1, 5 and 15 min TF. Both 1 and 5 min fulfill the signal criteria
bit not 15 min TF. Then suddenly when 7 min are done of the 15 min bar, this TF
give the signal. Later when 13 min of the 15 min bar is complete, it drops down
below the signal criteria. Traditionally, now my signal in the chart will
completely disappear since only the last close of the 15 min is saved. But in
my case, I use a 1 min resolution on the higher TFs, therefore my Buy/Sell
signals will remain in my chart during the 7 to 13 min time of the 15 min
period and I will have a complete record of what have happened (in 1 min
resolution).
For example- throw in the below code in a chart with 1 min interval, and you
will see a MA for 1, 5 and 15 minutes. For easier viewing, I usually plot the
"staircase" over the actual values. Then add some Buy/Sell signals for the TFs
and Experiment with it.
Regards,
Jorgen
