[ts-gen] FOREX Issues with "select bars"

[Ken Feng]

When running, for BID/ASK:

select bars CASH:IDEALPRO:USD:JPY 4;

I get the following 402 WARNINGS.

Problem: 402 unexpected minus sign, input clamped to zero
For token text: [      -1] and type target [quantity]
predicted token type:  pos, scanner saw:  neg
Problem: 402 unexpected minus sign, input clamped to zero
For token text: [      -1] and type target [count%6lu]
predicted token type:  pos, scanner saw:  neg

I do not know what count is, but I am not surprised that for FX, they
have set the quantity field to be -1.  For Forex bars, most brokers
don't aggregate volumes.  So this really shouldn't be an
error/warning, in the case of Forex.

Note that the same errors/warnings come up when asking for BID or ASK bars:

select bars CASH:IDEALPRO:USD:JPY 2;
select bars CASH:IDEALPRO:USD:JPY 3;

Trade bars doen't seem to work:

select bars CASH:IDEALPRO:USD:JPY 1;
