{quote} Why would an order send be unsuccessful? (Forgive the lack of knowledge on coding) I would suggest: Instead of market entry, when price comes within 5 pips (user defined) of the level, the EA places a limit order. If there is already a limit order there, do nothing. This avoids problems with market orders... order send error or potentially multiple trades at the same time - and even avoid things like slippage etc... Thank you for the previous fix.

New parameter "Limit orders" would require new implementation of several functions - testing would be neccessary and it takes time.
Someday ..

I have a few questions if you would be kind enough to answer please: 1 - openLevelNearDistancePips Does this mean at default "1.5", it will take the trade 1.5 pips early, and at "0" it will trade exactly at the level? If yes - is TP calculated from entry or the from the level? 2 - missedLevelNearDistancePips and missedLevelRetrace Does this mean if market comes within "3" pips and moves away "10" pips, it will cancel the trade? If yes, the 10 pips is calculated from the level or from where price turned away? 3 - How do beTpConstInPips (default "-2")...

1 - openLevelNearDistancePips Does this mean at default "1.5", it will take the trade 1.5 pips early, and at "0" it will trade exactly at the level? If yes - is TP calculated from entry or the from the level?
Yes 0 trade exactly at the level.
Trade TP is calculated on current market open price [current bid/ask when we sell/buy] -/+ number of pips specified by tp - SL also.


2 - missedLevelNearDistancePips and missedLevelRetrace Does this mean if market comes within "3" pips and moves away "10" pips, it will cancel the trade? If yes, the 10 pips is calculated from the level or from where price turned away?
==
10 pips is calculated from from where price turned away -- closest distance within 3 pips to level price.

Let me describe Buy order check:

- get "lowest recent price" [this should be changed "lowest recent price" is : lowest price searched within last 30 bars - this should be changed to n bars from EA start or something configurable - when one uses 1H tf or above it could produce spurious results]

- calc "missed level price" = "target price" + _missedLevelNearDistancePips
- calc "retrace price" = "lowest recent price" + _missedLevelRetraceDistanceFromNearPips
- get "ask price"
- if "lowest recent price" is above "target price" and below "missed level price"
and also current "ask price" is above "retrace price"
level is considered missed



3 - How do beTpConstInPips (default "-2") and beConstInPips (def "8") and tsConstInPips (def "0") work?

a.
beConstInPips ,beTpConstInPips :
After order is opened price must travel beConstInPips pips in favor [go up when u buy] to set SL to beTpConstInPips .
When beTpConstInPips =-2 your SL is set to 2 pips loss.
When beTpConstInPips = 0.5 your SL is set to 0.5 pips
When beTpConstInPips = 0- that is basically break even

When beConstInPips is set to 0 - no SL manipulation is performed.

b.
tsConstInPips - this is trailing stop,
fires after break even is set ,
and price advances more than tsConstInPips pips in favor (above open price when buy)
if 0 - does nothing
if beConstInPips also does nothing



4 - How does maxSpreadInPips (default "3") work?
Market Order wont open unless bid ask diference is 3 pips or less.




5 - What does skippedTicksPriceMoveInPips (def "1.0") mean and how does it work?

EA is trying to process every tick and apply logic described in above points.
_skippedTicksPriceMoveInPips causes above logic to fire off only when current bid price mover more than 1 pip from last processing bid price.
Missed ticks parameter allow to use more EA instances on given VPS.
When 0 - it tries to process every tick - and still misses some of them due mt4 ea thread slowness.

Thanks again for the tool. I took a few moments to think how I would have wanted things... and I have a few ideas. My suggestions to improve your EA: 1 - Option for EA to draw a line on the chart at the levels (with choice of colours for longs and shorts) 2 - Option to include fixed ECN commission charges into the risk (I want to risk 1% total including fees) - (would also need to specify how much $ the commission is per lot) 3 - Idea: instead of specifying Long/short for each level, EA automatically checks: if the level is below market - its a...

1,2,3 - todo
4 - someday todo, market orders get sometimes better price.
5 - hidden SL? why? one big visible initial 100 pip SL and another small 10pip hidden SL. Besides I have no exp. with hidden SLs.
6 - code consists of many small files, so i must extract subset of my code tree to separate repository like tfs or bitbucket.
Subj. to consider.

Idea of hidden SL (or lage SL which moves down to 12 when price gets very close) is to avoid potential stop hunting.

Thank you for the explanations. Good job.

Then we have small and big SLs where big one is set on trade.
Whenever u got spike that is a SL hunt and it hits small SL what to do ? Wait till large SL is hit?

And if price approaches short SL in calm way - close trade, right?
--
What params would describe such process ?

0 big sl is put to _SLPips
1. _SLHiddenPips - there goes small one, if zero then is ignored
2. _nSecondsHiddenSLWindow

if in recent n seconds price hit hidden sl and did not come back- then close trade.

or what else?
Any ideas?

Hmm...

I think SL at 20, then if price goes -10 pips, move stop to 12.

If price spikes past 12 - should close immediately... (all these should be optional).

I think I found another error (or it's the same one in another format)

UsdJpy 116.49 on 9/1/17
Trade opened at 116.481 (0.9 pips better) - went to profit

Then price went back down to the level after about 10 mins - and EA took another trade
So basically, it took the trade again when level was re-visited after a few mins (see attached).

I think the EA checks if a level has been invalidated (price came within 2 pips - went to target) - but does not check if level was actually touched and then went to the target.

After price hits a level and goes to profit, then re-visits the level - if you turn on the EA at this moment - it will take the trade.
The EA should not be taking this trade (regardless of whether it traded it before) because the trade is over and so the level is now invalid.

To fix it: EA checks if price came within 2 pips OR touched the level - and went to target (or SL) - if yes then invalid level - no trade.

Another suggestion for the EA:

- Option to make SL/TP based on the level - not the entry of the trade.

E.g. level is 100.00, so TP is 100.10 (regardless if the entry got 1 pip better or worse).

Thank you once again for the great job on this useful EA.

7.
U want me to add additional check as follows :
Whenever EA is restarted check if in the past level was crossed [within 30 last bars that now is a constant number of bars] and if positive,
set a flag on the level pointing that this level was traded.

right?

Well im wondering if add it with a parameter or not.
OK, lets put it onto : todo list.



Anyway , just for now : please keep in mind that
all levels are restarted whenever U restart EA.
So : whenever u restart this EA check if any of those levels was hit.
And if positive remove its price or side by : setting price to 0 or setting its side to "missing"

Today I want one more point to todo list :

9.When level is to be opened
but price was appoarching in last

_checkPriceSpeedWindowInMinutes=1 in minutes
and swept more than
_checkPriceSpeedMaxDistanceInPips=20 in pips

then level is flagged as tested but no trade is going to be opened.


Gosh, 9 points to implement..

Hi.
Those 9 points in a pack made it complicated to deliver
without issues so for now there are :

3 - Idea: instead of specifying Long/short for each level, EA automatically checks: if the level is below market - its a buy, and if above market: sell
new option to open : auto_retrace - short when price is above level and long when below.


9 - fast move filter - variables as above description says

10 -
fixed non trading time : price is processed in a normal way [level Is set as traded if price spikes to a level]
but no trade is opened.

I got some pm that was telling about turning off trading for 15 minutes before and after news

u can do it by turning on and off take14 or take15 variable = ie check yr server time and during expected nfp at 15.30
set to false take15 variable = turn off opening a trade for an hour

Defaults are slightly different than described in prev post:
_checkPriceSpeedWindowInMinutes=1;// check one minute bar with current bar to check price movement
_checkPriceSpeedMaxDistanceInPips=13; // if price swept more than 13 pips in a previous checkPriceSpeedWindowInMinutes bars and current - do not open a trade , but sign it as traded

Ad todolist point 8 :
SL and TP are set according to expected entry.
If u set openLevelNearDistancePips=0
and tp=10 then tp always will be at expected entry plus 10,
ie 100 and tp is 100.10
