Hi

In database setting, try " show day session only", instead of "show 24 hours trading"

  Hi Tomasz,

  I don't know what to say. It doesn't work.

  Your assumption 1 is correct, I believe: see the
  IntradaySettings.png.

  Your assumption 2 is *absolutely* correct. In fact, I do not exit
  same day, anyway (unless I override, which I rarely do). Here is my
  exit:

  ApplyStop( stopTypeNBar, stopModeBars, delay, True, False );

  I have had this code a long time, and RT results and trading results
  are never off by even one single yen -- other than fast-market trade
  entry miss or something like that. But it is accurate, realistic,
  and works -- the code I mean. But I cannot, using my eSignal
  one-minute database, isolate AM and PM entries. I have tried, on my
  own, to do this FOREVER, and I cannot do it.

  All I do is two things (other than what I would do with my master EOD
  database):

  1) Change periodicity to 1 minute (see file)

  2) Append 'AND Timenum() <= 120000;' to the end of the Buy statement.

  Then I backtest.

  But I generally get *no* trades as a result when I backtest after
  doing this. For example, using either last n days = 2, or using From
  2/7/2007 To 2/8/2007, I get no trades. That's wrong. There were
  four signals, three yesterday and one today. One of the trades on
  2/7 (yesterday) was at about 9:30 AM. I didn't dream it.

  Looking back, say, 100 bars, where I would have dozens and dozens of
  trades, I get maybe 4 to show up. That's not realistic. It's flat
  out way wrong. I know from years of experience most of my entries
  come in the AM session. Off hand, I'd say it's 2-1 or higher.
  Naturally, now that I am accumulating a longer and longer intraday
  database, I'd like to isolate these instances and test them.

  I cannot.

  Using the RT database in daily mode (with periodicity set at daily),
  there is no problem backtesting. But of course I'm *not* able to
  isolate signals by using Timenum() that way. Not that I can isolate
  them in any case, mind you.

  This is, to say the least, excruciatingly frustrating for me. I
  don't believe I am completely stupid, obviously, and I cannot see why
  this (apparently) simple little thing will not work for me.

  This is the *reason* I bought the RT version of AB years ago, and why
  I started subscribing to eSignal immediately when it became available
  in Japan. And on top of that, I knew the first few years of
  subscription would only serve to build up a database, and that I
  could not do realistic intraday testing until I had sufficient
  instances and data to draw reasonably valid conclusions from.

  I want to throw up now. ^_^
