Hi,
I'm new to this list, and new to AmiBroker, and very excited by this
program!
Alot of my prior experience is with TradeStation, so I'm somewhat used
to driving that interface. Hence, I may have a few questions that are
on the simple side for skilled drivers of AB. I hope you all will
Hi all.
Is it possible to have charts built on a black background and charts
built on a white background present and displayed at the same time?
My initial impression is that the only way to change the background
color of charts is via the global preference setting ...
Is there a way to link charts by symbol and have different timeframes?
Can this now be done? (AB 5.0)
I'm not seeing Buy/Sell arrows after a backtest either, despite
right-clicking and selecting 'Show Arrows for Actual Trades' in the AA
window.
Why could this be?
