# NinjaTrader 8 AddOn to convert NRD (*.nrd) market replay files to CSV (*.csv)
(based on not yet documented MarketReplay.DumpMarketDepth feature)

Quick Start

1. Download the latest zip file with AddOn from Releases
2. Import AddOn into NinjaTrader 8 via Tools / Import / NinjaScript Add-On...
3. Open NRD to CSV tool via Tools / NRD to CSV
4. Press Convert button to convert all *.nrd replay files (could take some time to proceed)

Filter files to convert

You can specify filenames to convert with semicolon-separated regular expressions (experiment here):

• Convert only Gold Commodity futures: GC
• Convert several instruments: GC; HG; 6E
• Convert files with names related only to December 2021: 202112\d{2}
  Means: "2021" "12" <any 2 digits of Day>
• Convert files with names related to all Decembers of Gold Commodity futures: GC.*\d{4}12\d{2}
  Means: "GC" <any chars> <any 4 digits of Year> "12" <any 2 digits of Day>
