Multiple Entries on a Single Bar

Someone must have solved this by now. My conditions are met on the close of the previous bar and an order is entered. However my SL is hit before the present bar closes (hourly chart). Since the conditions still exist from the previous bar, another order is entered. SL hits again before bar close and another order is entered. I've had up to three orders on one bar.

Anyone have simple code to solve this?

I had this same problem, and it took a while to figure out a work around.
If you are trading complete or open bar strategy, you can add
Volume <= 1 to your Buy entry and Sell entry block of code, for backtesting that is what I do. As far as live, I'm sure you would run into problems with slippage doing it this way. I guess you could increase it to a number that is higher or equal to the slippage your strategy will allow.

For every tick testing I do it by using the Envelopes indicator. Say I have a SL and TP of 100 pips, I would use Envelopes and High and Low. Set your Envelopes PER to 1, Price to OPEN, and Deviation to whatever your TP and SL are (in this case it would be 1.0, make them slightly smaller to account for spread, so 0.90, 0.80, etc.) Now if the current High or Low of the bar has not exceeded the Envelopes (Upper Lower Bands) a new signal will be generated, if the current bar High or Low has, then the signal will be discounted.

I know that someone has a better and cleaner solution, but these are the ones that I am aware of. Hopefully of some help to you.
