Symbol Data

Historical Bars Data

To get the historical price data of a symbol, follow these steps:

  1. Create a ProtoOAGetTrendbarsReq message.
  2. You have to fill the message fields with the trading account ID (not login number), symbol ID, period (time frame), and from/to timestamps, which are in Unix time milliseconds, the timestamps are subject to some limitations that you can find in the message reference table.
  3. Send the message, and you will receive a ProtoOAGetTrendbarsRes message, which will contain the historical data on its trendbar field.
  4. Transform the data from relative format to actual price format, To do that you have to use the trend bar low and divide it by 100000 and round the result to symbol digits. Then for getting high, open, close price levels, first add the trend bar delta level of each to low. At last divide each by 100000, and round the result to the symbol's digits.
  5. Now you have the historical price data for your requested time period.

Historical Tick Data

You can get the historical tick price data from the API.

To get the tick data follow these steps:

  1. Create a ProtoOAGetTickDataReq message.

  3. Send the message, and you will receive a ProtoOAGetTickDataRes message, which will contain the historical data in its tickData field.
  4. Transform the data from relative format to actual price format, To do that you have to divide each tick by 100000, round the result to symbol digits.
  5. Now you have the historical tick data for your requested time period, there is an "hasMore" boolean field on ProtoOAGetTickDataRes, use it to check if there is more data than the amount returned.
