A control to not repeat the operation
1)
static datetime lastbar;
global variables are always 'static'. Static is meaning full only within an function like start() or OnTick().
2) define a static or global variable which is set to OP_BUY or OP_SELL when your EA send an email and allow the next email only if the signal has changed - not not merge buy and saell the way you did:
if ((buy_condition_3 && buy_condition_4 && buy_condition_5 && buy_condition_6 && CWHH>OWHH && CDHH>ODHH && C4HH>O4HH && C1HH>O1HH) ||
(sell_condition_3 && sell_condition_4 && sell_condition_5 && sell_condition_6 && CWHH<OWHH && CDHH<ODHH && C4HH<O4HH && C1HH<O1HH)) {but
static int trend = -1; // not defined
if (trend != OP_BUY && buy_condition_3 && buy_condition_4 && buy_condition_5 && buy_condition_6 && CWHH>OWHH && CDHH>ODHH && C4HH>O4HH && C1HH>O1HH) { trend = OP_BUY; .. }
else if (trend != OP_SELL && sell_condition_3 && sell_condition_4 && sell_condition_5 && sell_condition_6 && CWHH<OWHH && CDHH<ODHH && C4HH<O4HH && C1HH<O1HH) { trend = OP_SELL...}
Thanks Gooly, but would you please provide an example of variable i can use to detect wheter the signal has changed?
Many thanks

Many thanks guys.
However i discovered that ea isn't working at all. It sends me emails every hour but values are Always the same....
Would move from int start to onTick all the code fix that up?
Here's the updated code

You've already been given the answer in this thread
https://forum.mql4.com/66514#1006464
Why ask for advice and then ignore it when it is given?
ok man, i took the advice from the other post.
New code. I'm out now so i can't test it.
There is something i should change to make it work perfectly?
Thanks

lemming78: i don't want a second/third/fourth signal until the conditions present again.
Then Don't check for just a level, check for a change in conditions. Like honest_knave's post orstatic bool signalCurr=false; signalPrev = signalCurr; signalCurr=/*signal logic*/; if(!signalPrev && signalCurr) { /*new signal*/ };
To be honest, I can't work out what you are trying to do.
Why is Signal a bool ?
Where is Signal assigned a value?
You have bool res, but what do you do with it?
| Signal has no value. | static bool LastSignal=false; bool Signal; if ((Rsi1>50 && Rsi4>50 && RsiD>50 && RsiW>50 && CWHH>OWHH && CDHH>ODHH && C4HH>O4HH && C1HH>O1HH) { LastSignal=Signal; |
| If you want to alternate | enum signals = {Buy, Sell, NA}; static signals LastSignal=NA; if ((Rsi1>50 && Rsi4>50 && RsiD>50 && RsiW>50 && CWHH>OWHH && CDHH>ODHH && C4HH>O4HH && C1HH>O1HH && LastSignal != Buy) { LastSignal=Buy; |

Hello everyone. I wrote my first semi-ea. Meaning that it is discretional in that but i need to be advised whenever the conditions are met.
My problem right now is that the EA keeps sending me signals every hour, even if IT HAS ALREADY SENT THE SAME SIGNAL. THis is what i would really like to eliminate. Meaning: if you give me the signal i don't want a second/third/fourth signal until the conditions present again.
Try to make an example (in there cond
itions are a little bit demanding).
Suppose my ea must send me and email when rsi daily >50 and rsi W> 50.
Currently it would send me every single hour the same signal. I'd rather prefer that the ea sends me a signal when both turned down <50 or if rsi daily first declined down to 49 (no signal) to step up to 51 (signal). Essentially, send signals only when there is a mutation (keeping that conditions are still met). Did i make my point?
I tryied to put a control, a sort of boolean but it didn't work out. (bool SignalSent=False; in variables ---- SignalSent=True; just below the conditions and SignalSent=False; after the end of the if cycle.
Thanks to everyone.
