The algo strategy marketplace idea is not unique. There are lot of competing apps which allow you to do that. But as far as strategy creation goes, there are 3 ways apps go about doing it
1) Write software code - in python or VB or some other language (MQL for MT4, AFL for Amibroker, etc, Python for Quantopian and Quantconnect etc).
2) Drag and Drop of Blocks - Here a user has to drag and drop blocks and set the relation between them to set the conditions for signal generation of the algo.
3) Click and Choose - Tradetron condition builder comes in this category There are some which are similar to ours which have a point and click approach to condition building but they have limitations on selecting the number of positions attached to those conditions. Also we track the run time variables which your strategy generates and provide you those as keywords which you can use in your conditions to take action. (Eg: LastRepairedDate which can be used to create strategies for SIP plans .. All you have to do is set your repair condition to check if its 30 days since your last repaired date and if so, you add the same stocks to your portfolio)
So in essence, we are unique because ours in possibly the only tool which allows for a Click and choose condition building with multiple position mapping to those conditions thus allowing to build for complex algo strategies with ease.
Not only that, we also allow for a custom python code to be incorporated within your strategy thus having best of both the worlds. Tradetron also goes far beyond signal generation of an algo system. It does the complete trade management by placing the orders in tranches, adjusting prices to seek the best entries and exits, rolling over expired instruments to next expiry and finally closing the strategy.
As if that was not enough, Tradetron will allow you to make your successful strategies a money making business by allowing others to follow it and take trades in their own accounts for which you can charge them a fixed and a variable profit sharing fee.
