Hello,
There is no bug. If it says that position is not entered
because of insufficient funds it means
that desired position can't be opened with specified
size.
Most probably either your formula specifies wrong (too high)
size, or your round lot sizing
does not allow too small pos, or you don't have "position size
shrinking" option enabled.
If you have trouble, send the formula to SUPPORT and we will
point out the error in your formula.
Best regards,

Subject: [amibroker] a bug in portfolio
tester?
Hi,
I
am trying to test the scale in/out in AM5.2, and base the code on the AM
tutorial on scalein/out. I found that, sometimes, portfolio backtester doesn't
enter a trade, even though there are enough cash. For example, I set the
backtester initial fund to 100,000, max 4 open positions, and each position
will use 10,000, report to detailed log mode. It is very strange that
backtester doesn't enter the trade on some days, like 14/4/09 and shows
message.
CTV not entered because of insufficient funds
But there is
80,514.9 cash available. A trade only needs 10,000
Anyone has seen this
issue before? Is it a bug?
thanks,
Steven
