Start a branch as shown in the last post
Turn off the block as default. In your original blocks when your suspension condition is met, enable it Then it will start up. The first pass will turn off the buy and sell blocks (you need to enter your block numbers) In Once per minute. Enter 1. Specific the time, say, if 20 minutes, input 20 in the Pass n times block After the time you specify, it will enable the buy, sell blocks again after, say, 20 minutes After all, it turn off the block at the top of this branch (you need to check the block number referring to the top block). And the Pass n times counter is reset as well (you need to check the counter ID yourself)It will then wait for next suspension condition. Hope it works for you
