Combining your strategy, minus the S/R lines, so you do a long version and a short version in the same account, you get the following:
Start out with no positions, just markers where the positions should have been. You have a long and short position at each of these markers, and thus no real position currently.
If the market goes up, "replace" the positions that would have been replaced if you were trading the short plan only. This means buying at those values a quarter point below the old markers, using a limit order, and afterward selling at the new higher marker level, also with a limit order.
If the market goes down, "replace" the positions that would have been replaced if you were trading the long plan only. This means selling at those values a quarter point above the old markers, using a limit order, and afterward buying at the new lower marker level, also with a limit order.
After running through this a few times you will see that this is really nothing more than the following: When the market goes up a bit, buy at limit a bit lower. If filled, sell at limit a bit higher. Vice versa is done if the market goes down a bit rather than up.
With the S/R lines removed and choosing not to bet on market direction, you basically have a scalping technique to capture small moves in the opposite direction of the most recent move. Could this be profitable? Possibly, but only if your commissions are very low. The profit per trade is tiny.
Could the S/R lines make this more profitable? Possibly, but I have yet to see any S/R related system consistently make money over the long term. You usually have many small gains that are offset by fewer large losses (for fade bets) or many small losses that are offset by fewer large gains (for breakout bets). The net is usually about break-even long term minus commissions.
Could the bet on market direction make this more profitable? Possibly, but if you are good at predicting market direction then you don't need any of the rest of this. Such an edge is sufficient by itself.
If I have misunderstood your strategy then I apologize. I am just trying to offer up some of my insight, albeit unsolicited.
