Quantity -Position Size (Lots) step 0.01 = 0.10 Lots. Error?
Quantity -Position Size (Lots) step 0.01 = 0.10 Lots. Error?
18 Apr 2023, 10:57
Hi
Is this my mistake or not?
The step for Quantity is not working like it should in the parameter window. I've got ''Step = 0.01'' in the code (I also tried with 0.001) but when I press the up or down button in the Parameter window it moves by 0.10 Lot not 0.01 Lot.
I'm used to it, but for the newbies and for the clients who use my bot for free this is a huge problem. They've got small account balance and when they try to move the Position size (Lots) they move it by accident by 0.10 Lot when they press the up button and then they blow their accounts.

Hi there,
Can you share some code so that we can try it too?

However, perhaps it's acting the way it does because with some brokers like IC Markets, users cannot trade in 0.01 lots. I believe their minimum is 0.1 lots. Maybe that's the issue?
I would try you code on two different brokers that allow for different sizes. For instance, Pepperstone allows for 0.01 lots, so try it with Pepperstone and then IC Markets and see what happens?
IC Markets allows 0.01 Lot. I tried the bot on different brokers. The problem is the same.
I've found an already-built-in cBot by cTrader that uses Quantity. There is an error in 'Step = 0.01' '

Hi PanagiotisChar. I'm a big fan of yours. You helped cTrader become the best and most advanced platform there is. I have huge respect for you.

Just to be clear. Will this issue be resolved?
Have you tried the source code I gave you?
I would really like to see this working like it should be working:
[Parameter("Quantity (Lots)", Group = "Volume", DefaultValue = 0.01, MinValue = 0.01, Step = 0.01)]
public double Quantity { get; set; }
