I'll try to detail here what the robot does

CopyTrader - Detailed Operation

OnInit(

)

Creates/opens the SQLite database"CopyTrader.sqlite"

Creates two tables if they don't exist:

signals: to store active signals

signals_history: to store signal history

Initial Check (CheckInitialOrders)

Checks all open positions, for each position with the correct MAGIC_NUMBER:

Records in the bank as a "NEW" signal

Stores in control arrays (previous_orders and previous_positions)

OnTradeTransaction()

Modification of SL/TP(TRADE_TRANSACTION_REQUEST)

Detects whenSL/TPismodified (TRADE_ACTION_SLTP)

Checks if the position belongs to EA (MAGIC_NUMBER)

Sends "MODIFY" signal to the bank with new values

New Position (TRADE_TRANSACTION_DEAL_ADD)

Detects when a new position is opened

Checks whether it's a buy or sell (DEAL_TYPE_BUY or DEAL_TYPE_SELL)

Sends "NEW" signal to bank with position details

If it makes sense to make the robot copy in this way

Thank you in advance for your co-operation.

Another question, the real account, when I try to get the ticket, it comes up with a negative number, can you tell if that's the case? Can't you get the correct value of the ticket?
