Running several instances of the bot: ExecuteMarketOrder method does not return anything

Hello everyone. The following bot (see below) does work correctly when added to only one chart. However, when I add it to more than one chart, the bot does either

• only enter the first market order for only one of the instruments,
• or enter the first market order for instruments and only place the pending order for one of the instruments.

I have tried the following without success solving the problem:

• compiling the bot with Net4.x and Net6.0,
• using different Robot ID parameters for each instance,
• testing different instruments and number of instances.

I have seen that there are other people who have a similar problem: https://ctrader.com/forum/cbot-support/38105 I have programmed and tested the bot on Spotware cTrader (Public beta) 4.2.4 and the latest version of ICMarkets cTrader. I hope that you can help me. Find the journal and automate logs below.

Kind regards.
