There are many opensource bots which you can use directly, or tune them to your needs. There's no sense in making new bot for every new strategy, it would make maintaining such bots a nightmare. If you describe your strategy in detail, maybe we can tell you which one has functionality closest to what you want to achieve.
Could you please publish links of good bots (open source) that you think are good ones, so someone like me with no experience in trading could study them.
Thank you.
