Hello everyone,
I hope someone can help me solve an issue with my cBot.
First of all, I want to mention that I’m trying to learn how to create cBots, so for now, I’ve used a very simple code and tried to add a logic for creating pending orders:
When the conditions for buy and sell are met, the cBot should first ensure that there are no other open positions. If there are none, it should proceed to place pending orders at a fixed distance, configurable from the control panel.
Once a Buy order is triggered, the code should then cancel all pending Buy orders. Same thing for Sell orders. This option is also configurable from the panel.
Unfortunately, when I run the cBot on the cloud, the pending orders are not placed when the openBuy or openSell conditions are met.
Additionally, I receive this error message in the log, which I don’t understand:
Error | Crashed in OnBar with TypeLoadException: Could not load type 'cAlgo.API.ProtectionType' from assembly 'cAlgo.API, Version=1.0.0.0, Culture=neutral, PublicKeyToken=3499da3018340880'.
I also want to specify that ProtectionType is a parameter I am forced to configure; otherwise, the system tells me that the code for pending orders is obsolete.
I’ve tried searching online for a possible solution but haven’t been able to find anything.
I hope someone can help me resolve this issue.
Thank you in advance, and I’m including the code of my cBot below:
