With the SST Local trade copier studies you have a more flexible functionality.

• You can copy between running SC instances so you are not limited to a single trade service account. 
• Sizing is more flexible as you can scale with different sizes and also use a smaller size on the receiver end. 
• You can copy your trades over different trading instruments.
• You can copy only when a trade is entered on a specific chart. So if you only want to copy trades you initiate on your strategy X chart you can do that. Setting the transmitter chart origin and your specific TAG. Basically allowing you, for instance, to copy your scalps but not your swing trades.
• You can show a text on the chart where you have a study active, reminding you of the loaded functionality.

All in all you will have a lot more flexibility with the SST trade copier studies.
