Programatically disabling/enabling trading for all Signals

Hi,
1. Is that possible to disable generating of all orders coming from enabled signals programmatically (let's say from another Signal 'my Signal'). Is there any internal variable that we can set to stop trading for a while?

2. If I want all enabled Signals work from 11 AM to 3:59 (for US Stocks) - how I can do that without changing Session parameters. If I change Session from 11-3:59 - data before 11 is not coming into Chart and calculations based on Length of previous bars are taking from yesterdays values instead of today's morning values?

Obviously, I don't want to program all the Signals I use individually. Looking to find common solution.

These 2 questions will probably have the same answer.

Thanks, Victor

Hello Victor,

Let me answer your questions in order:
1) There is no such variable. By default signals/charts do not talk to each other. You can make them communicate using one of the following methods. Since MultiCharts 9.0 that is possible to control trading of different strategies/symbols from the Portfolio Money Management Signal. Please see Portfolio Trader for more information.
2) If you are looking for a common solution then the answer is the same - Portfolio Money Management Signal.

Besides using the Portfolio Trader (see Henry's reply above), you can also use the Command Line (`ChartCommands.CommandLine()`) to disable trading on a specific chart. For that, the signal needs to call the Command Line method with the ".at_toggle" parameter.

There's an example of that here: toggle auto-trading programmatically.
