Need simple coding help, how to prevent re-entry on same bar?

Hi guys,

I am a super beginner at MQL4, and I am actually using an online EA Builder - StrategyTune (strategytune.com/app/) to make my EA.

I am very happy with what I can do with it so far, but I met with a problem with my EA.

I am trying to make a very simple EA.

Timeframe: Daily

The rules are:

1. Price goes up by 1% from low of the day, Sell TP20 SL20
2. Price goes down by 1% from high of the day, Buy TP20 SL20

I have made the EA, and the entry and exit is correct.

But my problem is that after the EA exit a trade, it will enter into another trade. While I only want it to trade once within a day.

So my question is: What code do I need to add to prevent an EA from re-entering a trade on the same bar? keeping it to 1 trade only per bar?

Thank You in advance for any of your help!

By the way, I have attached my newbie EA here so you will see the problem with the multiple entries within the same bar.

The simplest way is to record the time of the trade (Time[0]) and then compare TimeCurrent() to the stored variable and take the appropriate action.
