Partial Close % Script

  • #1
  • First Post: Dec 11, 2019 10:01am Dec 11, 2019 10:01am
Hello FF Members,

I am looking for a simple script where you can choose a % of the position size to close out?

For example:

If I have a 0.78 lot size open and I want to close 30% of the position the script would close 0.23 lot size and the remaining position would only be 0.55 lots

Thank you.

Close by Lots or Percentage

Lot/s Close - according to Inputs Lots

Percentage Close - Single Position

  1. 50% profit close on 0.01 lot position is not possible - 0.01 is the smallest possible lot and controls 100% of position.
  2. In 0.02 lots position each 0.01 lot controls 50% of position profit/loss. A partial close of 25% is not possible - In this case the EA will close 0.01 lots on any percentage equal or greater than (=>) 50% - so 60% will close 0.01 lot.
  3. A 0.04 lot position has 4 x 0.01 lots. 0.01 = 25%, 0.02 = 50%, 0.03 =75% 0.04 = 100%.
  4. A setting of 90% will close 0.03 lots, setting of 75% will close 0.03 lots. setting of 70% will close 0.02 lots.

Percentage Close - Multiple Positions on Same Symbol

If more than one position is open the EA will partial close positions according to FIFO (first in-first out) - the oldest position will be partially closed first.

A = oldest order 0.05 lots. B = youngest order 0.03 lots.

  1. 50% close run -> action on position A -> 50% of 0.05 is 0.025 so A is closed 0.02* lots -> 0.03 lots remains open.
  2. 50% close run again -> action on position B -> 50% of 0.03 is 0.015 -> so 0.01 lot closed on A -> 0.02 lots remains open.
  3. 50% close run again - action on position A -> A=0.03 lots and 0.01 lot closed -> 0.02 lots remain open,
  4. 50% close run again -> action on position B -> A=0.02 lots and 0.01 lot closed -> 0.01 lots remain open,
  5. 50% close run again -> action on position A > A=0.02 lots and 0.01 lot closed -> 0.01 lots remain open,
  6. No more % partial closes are possible.

* On a 0.05 lot position each 0.01 lot has a weight of 20 % (0.01/0.05x100 = 20%) -> 0.03/0.05x100 = 60% and 0.04/0.05x100 = 80%. On 0.05 lot position percentage between 60-79% will close 0.03 lots (60/100x0.05 = 0.03 lots) and 80-99% will close 0.04 lots (80/100x0.05 = 0.04 lots). 0-19% will close no lots (19/100x0.05 = 0.0095 = 0.00 = no lots). 20-39% will close 0.01 lot and 40-59% will close 0.02 lots. On a 1.00 lot position 2% will close 0.02 lots (2/100x1.00=0.02 lots) and 25% will lose 0.25 lots (25/100x1.00 = 0.25 lots).

A= oldest. A = 0.01 lot. B = youngest. B = 0.04 lots.

  1. 50% close run -> action on position A but not possible so EA moves on to position B and closes 0.02 lots -> 0.02 lots remain open.
  2. 50% close run again -> action on position B (A not possible) -> B=0.02 lots and 0.01 lot closed -> 0.01 lots remain open,
  3. No % more partial closed are possible.

A = oldest. A = 0.04. B = youngest. B = 0.01.
as previous but reversed.

Phylo, I have tried the scripts and found them to work IAW Last In First Out (LIFO) and not FIFO. Any chance you could take another look at them?

- Your observations are not correct but there is a FIFO anomaly regarding mixed orders (market buy and Sell)

Requirements: Pen & paper. Write down the following in rows -> last 2 numbers of order number + order open time -min:sec + order type (B or S) + Order of close after each script operation (1,2,3,4,5).

- Example 1: Open 5 x 0.01 Lots Sell Orders - Order #1 is earliest and Order #5 is last. Operate Script Partial_Close_defaults_D at 0.01 Lot. Order #1 is closed 1st, Order #2 closed second, etc., etc., and Order #5, the last order to be opened is closed lasts - FIFO.
- Example 2: Open 5 x 0.01 Lots Buy Orders - Order #1 is earliest and Order #5 is last. Operate Script Partial_Close_defaults_D at 0.01 Lot. Order #1 is closed 1st, Order #2 closed second, etc., etc., and Order #5, the last order to be opened is closed lasts - FIFO
- Example 3: Open any number of 0.01 Lot Buy and Sell orders at random. Operate Script Partial_Close_defaults_D at 0.01 Lot. Buy Order #1, the first Buy order opened, is closed, then Buy order #2, the second Buy order opened etc., etc., until all Buy orders are closed FIFO. After all Buy order are closed FIFO all Sell orders will be close as FIFO.*

* Summary: When orders are mixed the scripts closes first ALL Buy orders as FIFO then ALL Sell orders as FIFO but not in mixed order according to FIFO. (there is no LIFO, though).

I do not have time at present to amend the scripts operation regarding mixed orders - if, I get round to it I will notify at your [Shouts].

Phylo,
There was no mixed orders, all buys. Bought 1st lot, then 2nd lot and finally 3rd and final lot. Applied the script 'Partial_Close_defaults_A.ex4' and it closed 50% of the third lot, not the first or second. It was doing LIFO.

- Your observations are not correct

Here test with Partial_Close_defaults_A at 50% close

Key:
Order of orders opened: 1, 2, 3, 4, 5
Last two digits of order number: #99, #00
Order open time: mm:ss (10:26, 10:27)
Lots size:0.02, 0.01
Order type: B = Buy

1. #99 10:26 0.02 B
2. #00 10:27 0.02 B
3. #04 10:28 0.02 B
4. #05 10:29 0.02 B
5. #09 10:30 0.02 B

From the above it will be noted that 1. #99 - 10:26 is the first order opened, 2. #00 - 10:27 is the second and 5. #09 - 10:30, is the fifth and last order opened.

First operation with above script (50% close)

1. #99 10:26 0.02 B (this was the first order opened)
becomes
1. #23 10:26 0.01 B (#99 has become #23 with Lots = 0.01 and NOTE: the time stamp of #23 is the same ex #99 - namely 10:26)

NOTE: The remaining 2nd, 3rd, 4th, 5th orders are unchanged. Why? because FIFO.

Second operation with above script.

2. #00 10:27 0.02 B (this was the second order opened)
becomes
2. #27 10:27 0.01 B (#00 has become #27 with Lots = 0.01 and NOTE: the time stamp of #27 is the same ex #00 - namely 10:27)

NOTE: The remaining 3rd, 4th, 5th orders are unchanged. Why? because FIFO.

Third operation with above script.

3. #04 10:28 0.02 B (this was the third order opened)
becomes
3. #40 10:28 0.01 B (#04 has become #40 with Lots = 0.01 and NOTE: the time stamp of #40 is the same ex #04 - namely 10:28)

NOTE: The remaining 4th, 5th orders are unchanged. Why? because FIFO.

The final result -FIFO.

1. #23 10:26 0.01 B
2. #27 10:27 0.01 B
3. #40 10:28 0.01 B
4. #46 10:29 0.01 B
5. #51 10:30 0.01 B

Summary: All orders have been closed 50% and all orders have retained original time stamp - all orders have been reduced 50% sequentially in accordance with FIFO.

Edit: I forgot to take before and after shots of the Terminal and only have after - sequential step by step shots would have been better - anyway, gotta go - cheers.

Edit: As an amusement I decided to close the above with Partial_Close_defaults_D at 0.01 lot. As all 5 position are now 0.01 lots running the script will close all position according to FIFO. So here we go

First script run - one would expect order 1. #23 10:26 0.01 B to be the closed.

If you using an interpreter the above statement does not make sense.

The Lots Size and BE distance can be assigned from the Inputs Tab according to User requirements.

Assigning a Hotkey is not dependent on Lots Size or BE distance.

Coding a Hotkey to initiate a trade operation, in this instance, is not a workable option.

What I mean is that when I assign a hotkey to the script it opens the window an you need to type the ammount cause is 0.01 default. Would be nice to have x position size bigger than 0.01 by default and BE too in order to activate the partial close as faster as possible via hotkey with no typing

That would mean I would have to code scripts with default parameters for different request - I do not have time.

The [Save] and [Load] facility is the closes option for greater efficiency.
