Post From: Simple Replay of Multiple Charts on a High End PC lags in Accurate Trading System Mode

Hi SC Engineering,

Just wanted to share something from the code:
struct s_ChartReplayParameters
{
  int ChartNumber = 0;
  float ReplaySpeed = 1;
  SCDateTimeMS StartDateTime;
  int SkipEmptyPeriods = 0;
  n_ACSIL::ChartReplayModeEnum ReplayMode = REPLAY_MODE_UNSET;
  int ClearExistingTradeSimulationDataForSymbolAndTradeAccount = 1;
  n_ACSIL::ChartsToReplayEnum ChartsToReplay = CHARTS_TO_REPLAY_UNSET;
  int ProcessingStepInSeconds = 0;
};


Above ProcessingStepInSeconds is integer and cannot be set to a decimal value like 0.1 or 0.01, which is currently supported in the Sierra UI. If for example I want to replay multiple charts in realtime (i.e. speed of 1), by setting processing step in seconds to 1 I am not fully utilising my chart's update interval. Ideally this should be floating point number.

It is not a big thing since most of my replays are done in high speed, but just something for the future.

All the best,
