You need to write a java or vb script to delete data between certain bars

Subject: [amibroker] eSignal's really bad data

The situation:

Tokyo closed for a string of national holidays from 3 PM on Tuesday,
May 2, until today, May 8, at 9 AM.

eSignal has created erroneous, laughable data, of the one-minute bar
variety, for both May 3 and May 4.

Every symbol.

The Tokyo data for today seems at least <lol> as (un)reliable as
usual.

So, now I have a database full of data for May 3 and May 4, and I
assure you that NO trades of any kind took place on the TSE on either
of those dates.  Somehow, they've even got index data on those dates.

Didn't happen; they are abusing some substance.

eSignal will (eventually) correct their server(s), I would guess.
However that will not fix my database, unless I do a force backfill
symbol by symbol, as they outlaw per-database backfills, and I now
have data through May 8, which means they are not going to replace
anything earlier -- even though it's data they made up out of thin
air.

I really do not want to do this nearly 200 times. Does anyone have an
automated answer to deleting all data for all symbols on May 3 and 4?

Yuki
