I have been using the trade tiger for almost a year. Before registering an account I did check the reviews from existing users who complained of bugs within the software but I though of giving it a try. After a year here is my review.
-There is a bug which will ignore your buy or sale. This may not occur often but the fact it is present and will occur only if you have pitched a big profit during the intraday.
I prefer trading mainly in intraday, I have come across such situations where I have tried to buy or sell lots three to four times at a given time. But the buy/sale would be effective only after I was at loss.
So think twice before you open an account with them.
