I have imported data from an external program into a database. I can plot the data in the charts. I am now trying to set up a neural network using
inputs from the database field. The neural network will work when I run it with only inputs from QUOTES. When I add one of the inputs from my data,
the neural network sets up , but when I try to train it I get the following error box.

Info Dialog Box:
Error in formula:
Syntax error on "_", state 1324, expecting: IDENT
Error while compiling formula.

The field I am trying to use is a binary indicator with a range of 0 to 1. In the neural network, I have a Database field selected named 'predictedneuralindex'
with a WS of 1 and a scaling from 0 to 1. I have tried all three parameter options of 'LastData', Zero, and NA.

I am on a trial of Quantshare and while I like a lot of the features, importing csv data into a database and using it in a neural network is a requirement.
Any suggestions?

Hello Bryan,

Sorry about that, we will fix this in the next release.

There is another solution to use databases data:
- In Inputs control and under the "Type" column, select "Formula" instead of "Database Field".
- Click on "Select"
- Type the following formula: GetData("database name", "field name")

Don't forget to replace "database name" by the name of your database and "field name" by the name of your database field.

Trading financial instruments, including foreign exchange on margin, carries a high level of risk and is not suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
