My robot is performing excellent on backtest and Demo testing, but it's making losses on Live account

Hello, I need help, my robot that i created myself is performing exceptionally well on backtest and it's equally doing great on Demo account, but when i put it on a live account, it's making more losses than profit.

It's breakout strategy EA, when i used standard account it was making more losses. But when i switched to ECN account, it made some profits but sometimes it also run into some losses. The result is not compared to Backtest and Demo.

I know spread and trading conditions on live account is different abit. I used Spread filter on the EA and ATR, but they they're not helping in making the accuracy of the EA better.

Please who is willing to assist in improving the performance of the EA?

I have the code, compiled file and the logic. I just need improvement on the performance on Live account
