Need Mt5 EA code to control One Trade Per Bar

Hi,

My EA opens trade on new bar whenever certain conditions are met. the problem is that, if i close the trade on current candle then it will immediately open new trade because condition is still valid. and therefore I need a MT5 Code to control my EA to open trades only once on each bar whenever my trading conditions are met.

The EA code should strictly allow to execute my open trade function to operate only for once on each bar regardless of any timeframe.

For Example: My EA opened new trade on a very new bar of 15 minutes timeframe....... after 5 minutes I closed that trade....... Now what I need is your Code should not allow my EA to open another trade on this bar.

The whole requirement is to let EA to execute trade operation only for once in a bar. once it is executed for once it should not execute again on this bar even if there is no open trades.

Code should be simple and short, neat and clean.

Thanks
