I suppose you are referring to algo trading (algorithmic trading) wherein you can trade with formulas and programs. Currently, this algo trading is allowed only in the case of institutional traders and in the case of proprietary traders. Brokers are allowed to offer very limited types of such trades to clients but then the onus is on the broker to ensure that the client is fully informed about the risks.

Auto trading by itself is not a profitable activity. Auto trading becomes profitable in the case of large institutions because of the low latency servers that they use and the large volumes that they do. If you are looking at small volumes, there is not much value addition that auto trades can bring to you. Many of the conditional trades, you can place even today on your existing trading platform.
