Trading platform that has market replay?
- Thread starter shots fired
- Start date
Every usual suspect software vendor offers "market replay", "bar reply" or whatever the freak is it called. It's a standard feature nowadays.
bar replay and market replay are different
What does market reply?
bars don't exist in the market. only sales and quote data (aka market or tick data) does.
bars simplify working with market data, both for users who are not data sensitive and for platform creators who serve only this audience.
outside of a software simulator you can't actually get filled on a bar. in the real market and in accurate simulators you are always filled on sales (against quotes).
for some the distinction doesn't matter, but there is a difference. also some platforms (eg almost every retail platform) may fudge and call bar replay a market replay.

Ticks are bars also. A tick bar is a bar where Open, High, Low, Close are equal. I don't know whether you want to replay invisibility. And of course you could replay a 20 tick range bar or a 5min bar or ... with 1-tick step. Probably that's what you mean.
i was using tick as in tick data, eg timesales + some level of depth.
a tick bar is still a bar, although for retail platforms that don't natively support tickdata sometimes they will try to back in some of the same data as a work around and to be able to check a marketing box that they have the capability.
