Does downloading historical data erase saved market replay data?

[Spiderbird]

Hi all,

Title says it all really. I'll fill in some details.

I have about two months of recorded data for a few securities that I recorded with the Market Recorder. But, there are a few days that are missing, or a particular day of the week was only partially recorded.

If I choose to download historical data from my broker for those missing/partially recorded days (which is IB), will it overwrite any existing recorded market data from my Market Replay connection?

Note: I understand IB doesn't offer tick data, but I'm looking for OHLC and Volume data for my own calculations.

Thanks in advance for any answers!

Yours,
Spider

Nope, MR data and historical data are two different things.

Great! Thanks for the clarification.
