Support and resistance levels are likely to break during the US session because there is a lot of liquidity during this session. Knowing this, my opinion would be to use 5-10 minute expiry on bounces, because the chances are good that the level will break.
When you trade a support level that broke and became a resistance level (or vice versa), you can use longer expiry times like 15-30 minute expiry. I say this because you are trading with the trend. This is because you are trading with the trend.
Counter trend moves really are not a good idea to use during the US session. If you want my advice – stick to the trend. Your ITM margin will also be much greater than counter trend moves.
