Current balance is known when order is created. You can add it to fn arguments and simplify it a bit as Option won’t be used.

@caglaryucekaya Also, there are 4 tests failing that have been stable:

docker_tests::docker_ordermatch_tests::test_zombie_order_after_balance_reduce_and_mm_restart
docker_tests::order_should_be_cancelled_when_entire_balance_is_withdrawn

And these should be related to this PR changes. Please check them and fix.

Great work! 🙂 @sergeyboyko0791 @shamardy Please take a look too.

I think we need to add balance loop if it doesn't exist for taker orders that get converted to maker in handle_timed_out_taker_orders, it would be good to also add a test case for this to not forget about it in the future if we were to change anything.

-        }
+        ordermatch_ctx
+            .makerorders_ctx
+            .lock()


@artemii235 here's the lock inside the loop

It's not a problem here as Taker->Maker order conversion is not that frequent :)

@sergeyboyko0791 Waiting for your review 🙂

Amazing Work 🚀 !

Great progress!
Please consider my suggestions

                    if !orderbook.order_set.contains_key(uuid) {
                        missing_uuids.push(*uuid);
                    }
                }
            }

            for uuid in missing_uuids {
-                let order_mutex = match ordermatch_ctx.my_maker_orders.lock().get(&uuid) {
+                let order_mutex = match ordermatch_ctx.makerorders_ctx.lock().orders.get(&uuid) {


I think it's better to add MakerOrdersContext::get_order method

Only one non-critical comment. If you have time, you can fix it, otherwise we can merge this PR

+    }
+
+    fn spawn_balance_loop(&mut self, ctx: MmWeak, order_base: &str, balance: Option<BigDecimal>) {


It's better to take order_base: String by value.

Sure I'll fix it
