Take half off without leaving your chart
Scaling out is where a lot of strategies actually make their money, and it is exactly what most bridges leave out. TheConnector accepts a partial close as a first-class command, in two forms: a percentage you configure once, or an exact volume written into the alert when you want that trade handled differently.
Percentage, or exact volume
The percentage is an account setting, delivered to the robot ahead of time — the alert itself does not carry it. That keeps your Pine Script short and lets you change how much you scale out without editing a single alert. When you do want a specific trade closed by a precise amount, write the volume in the alert and it wins over the percentage: it is the more precise instruction, and you wrote it on purpose.
Change the percentage from your client area — no alert to re-edit
An explicit volume in the alert overrides it for that command only
The remaining volume keeps its stop and target — you are scaling out, not reopening
Closing what is not there any more
Strategies send close commands for positions that have already hit their target, or that never opened. TheConnector treats a close on a position that no longer exists as a harmless no-op rather than an execution error, and it waits a short moment for an entry from the same batch that may still be in flight before deciding there is nothing to close.
- 01No false execution error in your history for a position that had already closed
- 02A short grace period covers the entry that is still on its way
- 03Rejections that are real still carry a reason you can read
Migrating an existing strategy
TheConnector understands the command vocabulary most TradingView traders already write, so a strategy that scales out today can usually be pointed at a new webhook without rewriting its Pine Script. The full grammar is documented, and the free tier lets you check it on a demo account before touching anything live.

The same alert can drive MT4, MT5 and cTrader at once
Frequently asked questions.
Do I have to put the percentage in every alert?
No. The percentage is set once on the connected account and delivered to the robot ahead of the command. The alert only says that a partial close should happen, and on which side.
Can I close an exact number of lots instead?
Yes. Write the volume in the alert and it is honoured exactly, taking priority over the account percentage for that command. The three robots honour an explicit volume identically.
What if the position was already closed?
The command is treated as a harmless no-op, not as a failure. A close aimed at something that no longer exists does not fill your history with execution errors.
Is partial close available on the free plan?
Yes, on all three platforms. It is part of the command set, not a paid add-on.
