cesas,
As stated, as you try and load a new chart it is very possible that you pull a different data set from your data provider. Many data providers have different servers storing slightly different data. As you reload it may send you to a different server and ultimately different data. PriceTypeSupported allows you to choose which price series you want the indicator to calculate on. It is of no value if your indicator was not programmed to use it.

cesas,
Not sure I understand you. As stated, keep the data the same, keep the settings the same, it will (for the most part) produce same results.

Indicator signals look the same when your data is the same. If you keep the data the same, you will have the same results. Just disconnect from your data provider and then your data will remain static. You will just pull whatever is stored in your NinjaTrader database.

If ninjatrader can only reload the data that it is not displayed, that is fine, but ninjatrader always reload all the data. I dont understand....I am confused |

cesas, under Tools > Options > Data - did you enable to store real time bar data? Otherwise NinjaTrader will load the needed data on connection. To review when it will load, please see this link - http://www.ninjatrader-support.com/H...ricalData.html

If you mean it reloads always the current day, then this is expected, please review this link I posted earlier.

not only the current day, multiple days, about 300 days ago, like the format data series configuration

cesas,
Data will always be loaded whenever one of the conditions in the link Bertrand posted occurs. Depending on your data provider it may or may not only load a portion of it. I believe some data providers only offer you data in chunks and you would be required to download the whole chunk.

cesas,
I'm not sure, but I don't think IB even holds 300 days of historical data. It is just refreshing up your chart to get it caught up based on the rules stated earlier.
