Well, because I do not want to work with brokers for any reason 🙂 No, seriously those are old friends we worked together years back in different financial institutions. They normally try to show off with their new products, but I always leave them frustrated after the conversation because they realize it is not enough what they did.
Anyway, the brokers can not do it for two reasons:
1. This is not their main job, they are brockarage
2. They do not want to clients to profit. So whatever they do, it wont be useful for the trader.
This is why EA Studio and FSB Pro are such great softwares, because they are created in favor of the trader.
