At the bottom of the Moonbot terminal there is a value with an API Load and an indicator that sometimes lights up green and sometimes red, what is it?

The “API Load” is the API load indicator. When you open new charts and place new orders, the scale will gradually fill up. If it is green, the load is small and within acceptable range, but if it is red and you hear a beep, it signals that the current API load is high or critical. If the indicator is red for a long time, after some time the exchange may issue a ban and prohibit receiving data on API from that IP address. During the ban you will not be able to trade. In this case, you need to analyze what caused the overload and reduce it, for example, close some of the charts or maybe you opened a lot of strategies, each of which began to expose a lot of orders. Then you need to disable some of the strategies or review their work, so that the number of orders does not lead to a load on the API. If the exchange sees that an increased number of requests from your IP above the permitted API limits, it issues a ban and blocks receiving data from your bot via API. Ban first written short-term for a few minutes, then exchanger automatically removes it, but if spam from you continues, the exchange again writes ban, but for a longer period. So be sure to monitor this indicator and do not overload API.
