Good Morning,
I'm new with Multicharts ,I like to use concurrentdictionary,
I used GlobalsDemoTrendPower to understand the mechanism of concurrentdictionary and I changed in it according to my needs ,
the code sends/receive open,close and high to simplify the task;

The problem that when I put the indicator and the signal, the transfer start at this moment and the historic data doesn't transferred .

As you see in this attachement

for me the historical data is important to code my trading strategies.

Do you have any suggestions???

and thank you by advance.

I believe you can use ADE (all data everywhere) to do this.
