Need to know how is that app going really need it all I use is my phone can't wait for it

Anyway, we can't give an accurate date as this can be delayed for any unexpected reason. This is exactly why major companies (ex: apple) don't give also an accurate date until product is fully released.. to avoid last minute inconveniences.

You don't need to worry, but start an algorithmic position (or some of them at a time) that suits best your needs in terms of timeframe, and stop it once our notification system warns you about optimal profit. The rest is up to our AI.
