One could make it work. But the order placement, timing and position management is what make a PL grow without the big draw downs. The "strategy" is edge neutral. All the profit and draw down risk is in the trade management. It would be a good starter "strategy" to work on your order-trade-position management methods.
I use Bollinger Band on equity curve for every system, have to judge by site if it works for all systems. When equity hitting upper band, reduce size, when hitting bottom I increase size. Has worked forme past 30 years.
I would not do that. This is kind of martingale strategy when you increase your position size after a serious of losses. You are not in the position to do that here. Better is only to increase your size when made gain(s). Martingale strategies are of high risk, you never know when there is a much higher drawdown when you increase your size. But that is me.
%% Good read + study ph11. He includes , but not limits equity curve trading to skip trades after consecutive wins; skip trades after consecutive loses...... The skipping after a certain amount of losses makes much more sense + profit for me. Hard to imagine how skipping trades after reasonable wins could help much; even though i skip trades last several minutes to close , usually + skip first 25 minutes or so after open, but that's not based on wins. And i have no rules against skipping resting orders on open......
