Get Symbol Bars seems limited
07 Jul 2020, 22:44

Hey guys, i'm having a hard time getting more than 198 Bars.

I'm trying with ,

Bars c = MarketData.GetBars(TimeFrame, SymbolName);

which gets me up to 127, and then with loadmorebars, can get up to 198, this is totally not optimal, so i went on another approach that is also not optimal.

a for loop that tries to get the bars I need for my code, but gets to a point where NaN exists in the array and it's unusable.

So, let's say I need to get 1000 Bars, how do I achieve this? Any idea?

Or what am I missing here?

Thanks in advance!!

Hi tperalta82,

You should be calling the method until the desired amount of bars is retrieved. See below

            var bars = MarketData.GetBars(TimeFrame, SymbolName);
            while (bars.Count < 1000)
            {
                bars.LoadMoreHistory();
            }

RE:

Thanks a lot for your reply, that was one of my first tries, doesn't work, some pairs go to 128 others 120, got one to 198.

After the while the strategy stops due to a timeout because of this.

I even connected VS to make proper debug with breakpoints, and no, doesn't add more bars

Hi tperalta82,

No, you did not mention anywhere that this happens on backtesting. On backtesting this method is not supported at the moment. If you want to get more bars during backtesting, you need to start testing from an earlier date.
