how to make trigger when object com from indicator show up on chart and we make alert or Open order ?

There is a block named "Indicator appear", but it depends on the indicator itself. This block waits for the buffer to turn from 0 or EMPTY_VALUE to something that is different than 0 or EMPTY_VALUE. So if your indicator is... let's say "not standard"... then you should use Condition block(s). In any case, I will recommend you to check your indicator's buffers using "Indicator tester" block. With this block you will see how buffers work, and if they work properly then "Indicator appear" can be used

1. can we use fxdreema to build indicator , how ?
2. continuing previous question

• i still don't get it what is buffer and how to check it using "indicator tester" block
• if you don't mind please show us example how to test indicator buffer by giving us picture of blocks

this is my indicator properties on block "indicator tester" & " indicator appear "

[fxDreema]

1. No, and I can't tell you when or if it will be able to do that
2. https://fxdreema.com/documentation/gett ... indicators

[papaprabu]

thanks.. i quite understand now about buffer

1. how to use "indicatort tester" block ? should i place it after indicator appear block ?
2. what is the use of "indicator rise" "indicaytor is visible" ?

[fxDreema]

Right click on a block -> Information

Indicator tester works like this: https://fxdreema.com/demo/mt4-indicator-tester
Inbdicator rise detects when the indicator rises - the difference between it's current value and old (candle) value is more than some number.
Indicator appear is when the indicator was not visible and it turns into visible, this is for arrows and oblects like this. Of course, it works on a buffer level.

[papaprabu]

what if i wanna do this..
i've use block " indicator appear " & " indicator visible " it's not working
no open order

if i use block "indicator appear " it only open once per bar / every tick when the object appear. what if i still wanna open order on the next candle..
i'm wondering if there is block "check last object appear " or some like that

[fxDreema]

Using value of 1 for Candle ID for the indicator itself? (click on More settings)

Damn, how can you read this dark blue text on black background!

I can suggest to use a variable which will be updated to 1 when the upper circle is detected and to 0 when the lower circle is detected. Values 1 and 0 are optional. So you will have a condition where you will check this variable. If it's value is 1 -> sell, if it's 0 -> buy.

this is the blocks https://fxdreema.com/shared/911wFn3Cd

[fxDreema]

Yes, this is the way. Also works if you write it's name, but this one that is under "MQL name", which is valid variable name.

i still confuse..
coz if you see there is no input of the custom indicator that produce the upper & lower circle..
how the expert advisor determine which object is the upper or lower circle when there no indi that produce it.

that's why where should i put the custom indi that produce the circle ?

when i try this blocks https://fxdreema.com/shared/911wFn3Cd

it's only produce sell anda it's not suitable as i want.

nb : sorry this variable/constant things is kind new to me,, still confuse

[fxDreema]

And where is the indicator in this game? Put it where it needs to be in order to control those variables, it can be at top level somewhere. Just follow the logic. What you want it so modify some variable to 1 or 0 (or whatever else value) when something happens. Some condition? Why not.

By the way use Variables instead of Constants in this situation. Variables are what changes, Constants are for values that does not change within the EA, for input parameters.

[papaprabu]

here is the indicator..
it produce lower & upper circle..

let's say i wanna
sell only per candle after upper circle appear
buy only per candle after lower circle appear

please show me how ?
