Limit Order Manger EA and excess liquidity

Hi,

Can you assist?
I am searching for an EA that will stop execution of further limit orders once ‘x’ trades are open.

e.g I have 10 limit orders, 4 are hit (become open), the others are cancelled.

Kindly advise if you have seen this anywhere?

Wrong thread for the next question but I am also searching for data on when Bonds are redeemed and where there maybe excess liquidity in the system. Source where I can understand the mechanics around this.

Thank you
