I think you are missing the point about the feature that we are
looking for.
1. Suppose you have 1 min data.
2. You set up 5 min, 15 min, 60 min and 180 min charts on the screen.
3. During realtime, the last bars and indicators on the far right
are constantly changing as new data is received. Only that last bar
is changing.
4. What I would like to see is a way to go back in history and step
through my one minute data at say at some period like 2 min(some
multiple of my base data) and watch that last bar change just like
it does and realtime.
5. I am not looking to see completed bars move across the screen, I
want to see the last bar and indicators develop and change just like
they do in realtime. When the far right bar is complete, then the
chart would move over and we could watch the next bar develop.
6. This process could be controlled by hitting say the right arrow
key and the 2 min of time would go by. The calculation time could
be displayed in the chart bar title.
I also see that this is a problem with backtesting.
1. lets say you have 1 minute data and are using the 60 min chart
for your signals.
2. You enter a trade and set a profit stop and a stoploss.
3. If you backtest using a periodicity of 60 minutes, your stop and
limit can come in the same bar - so which one came first? This
leads to incorrect results.
4. If you backtest using a periodicity of 1 minute, you must
timeframe expand your all your indicators from 60 minutes to 1
minute. This works OK for the stop and limit. However, the 60 min
indicators are constant during each 60 minute period. In reality,
just as the price changes every minute, the indicators should change
every minute based on the current OHLCV.
Maybe there is a way to do this and I just don't know how to do it.
