Accessing Historical Data from Live Strategy

[typedef struct]

I have a strategy that needs to look at the prior n bars in order to calculate market conditions. Of course I can just wait for n bars to be processed in the strategy, but if n is large I'd like to pull that from historical data (rather than wait several hours/days each time the strategy is started in real time before trading).

How do I go about doing this? Thanks

You don't need to do anything special, other than making sure you have enough bars loaded in the chart you're running the strategy and in the strategy be sure to do a check of having enough bars (eg. something like CurrentBar > n where n is the number of bars you minimally need).

Hello typedef struct,
Welcome to the forum and I am happy to assist you.

Say, you want to get the value of a bar 10 bars back, then you can call the bar using the below code

if (CurrentBar < 10) 
{
   double close10back = Close[10];
}

Ok, great. I figured that when I started a strategy up, there would be no bars available until it had been running long enough to collect those bars. Good to know it can use historical bars automatically if they exist.
